Episcopal Vicar for the New Evangelisation


Episcopal Vicar for the New Evangelisation
Rev. Fr. Terence Pereira
A priest after the Good Shepherd’s heart, Fr. Terence’s great desire is to see all lay faithful learn and grow to be disciples of Jesus Christ. As the Episcopal Vicar for the New Evangelisation, he leads ONE in promoting the work of evangelisation and disciple-making in Singapore.
What is an Episcopal Vicar?
Can. 476 Whenever the correct governance of a diocese requires it, the diocesan bishop can also appoint one or more episcopal vicars, namely, those who in a specific part of the diocese or in a certain type of affairs or over the faithful of a specific rite or offer certain groups of persons possess the same ordinary power which a vicar general has by universal law, according to the norm of the following canons.
Can. 478 §1. A vicar general and an episcopal vicar are to be priests not less than thirty years old, doctors, or licensed in canon law or theology or at least truly expert in these disciplines, and recommended by sound doctrine, integrity, prudence, and experience in handling matters.

Cassilda Lim
It is no longer I who live, but Christ who lives in me. And the life I now live in the flesh I live by the faith of the Son of God, who loved me and gave himself for me.
- Gal 2:20
I provide strategic, pastoral and operational leadership to guide the office in our mission to catalyse the new evangelisation in the Archdiocese of Singapore.
Encountering Jesus deeply as a teenager undone every assumption and plan that I had in mind for myself. In Christ, I found the love of my life and my greatest treasure. I believe Jesus holds the key to every question, desire, heartache, dream and hope in life. This conviction shapes the way I lead and serve. Through leading, forming, and equipping others, I seek to create spaces where people can encounter the goodness and greatness of Jesus in their own lives.



Valerie Siew
Senior Manager
For surely I know the plans I have for you, says the Lord, plans for your welfare and not for harm, to give you a future with hope.
- Jer 29:11
I am blessed to serve ONE's evangelisation efforts through communications and engagement — sharing our mission with clarity, fostering collaboration and communion, and inviting others into the Good News that inspires all we do.
Little did I imagine that one day I would be working in the Lord’s vineyard! I began my professional life as a librarian, yet the Lord’s plans for me (Jer 29:11) unfolded through many twists and turns, leading me to where I am now — happily immersed in this mission of evangelisation. My faith journey remains a mystery, as I continue learning how great and wonderful God is. Through difficult relationships, emotional challenges, and anxieties, I discovered that God loved me and never gave up — sending help to overcome the roadblocks I faced.
As I learned to discern life’s realities more deeply, I began to see God’s hand inviting and shaping me, calling me to holiness, communion, and mission. I am far from perfect. There are days when I still feel anxious and worried about family, loved ones, and work. Yet I am growing in the grace to cast my fears, worries, and joys upon the Lord, saying, ‘Jesus, I trust in You.’ Today, I lift my hands in praise and thanksgiving to the Lord, who loves with an everlasting love (Jer 31:3).



Leonard Koh
Do not go where the path may lead, go instead where there is no path and leave a trail.
- Ralph Waldo Emerson
I serve as Senior Manager of Formation and Strategy at the Office for the New Evangelisation (ONE). I help parishes grow into missionary, disciple-making communities by guiding pastoral conversion, forming leaders, and shaping strategies that unite evangelisation, formation, and culture across the Archdiocese.
I’m in this mission because I’ve seen what happens when people truly encounter Jesus Christ - hearts come alive, purpose becomes clear, and ordinary lives become part of God’s extraordinary story. The Church changed my life, not as an institution, but as a living community where Christ is present and people walk with one another toward holiness. I believe the church can become a place where faith is real, hope is tangible, and love is visible. My desire is simple: to make Jesus known and loved, helping people meet Him and grow into all they are called to be in Christ.



Keith Neubronner
Now to him who by the power at work within us is able to accomplish abundantly far more than all we can ask or imagine, to him be glory in the church and in Christ Jesus to all generations, forever and ever.
- Eph 3:20-21
As part of ONE's Formation team, I help conceptualise and present different types of formation so listeners/readers discover how to live their baptismal calls with greater fidelity - one conversation at a time.
As a kid, I wanted to be a Power Ranger. As a teen, I wanted to be a writer. God's plan was to have me in ministry, being a channel of His supernatural power and using my charisms - including writing - for His glory. I'm glad I've pursued God's plan, bigger and better as they are from what I can possibly imagine.



Cheryl McAlea
Declare his glory among the nations, his marvelous works among all the peoples.
- Psalm 96:3
As the Publications Manager, I lead the strategic development and delivery of ONE's publications portfolio. I ensure that we create resources that serve as effective tools for evangelisation within our Singapore Catholic Community.
My prior experience in youth ministry laid the foundation of what it means to serve God our Father and His people. Ministry work transformed my relationship with Jesus. It gave me immense joy to contribute so humbly. After over 16 years of leading brand, content and communication projects, I now gladly use my skills to serve the Lord once again. As His mouthpiece, I serve and support the mission of cultivating more disciples to grow in and with His Kingdom.



Grace Yee
Each one, as a good manager of God's different gifts, must use for the good of others the special gift he has received from God.
- 1 Peter 4:10
I manage finance and administration to ensure smooth daily operations for the programmes team, allowing for the mission of the office to be carried out fruitfully.
Being actively involved in ministry work as a youth played a significant role in shaping my character and perspective on life. Having the opportunity to labour in the vineyard reminds me to stay grounded in faith and humility, and to treat one another with grace and love.



Vanessa Chan
Finally, beloved, whatever is true, whatever is honorable, whatever is just, whatever is pure, whatever is pleasing, whatever is commendable, if there is any excellence and if there is anything worthy of praise, think about these things.
- Philippians 4:8
I develop integrated marketing and communications plans for ONE. Through ways that are creative and relevant to today's world, I bring our vision to life and inspire people to live the life that God has called them to.
I am continually moved by the beauty and goodness in everyday life - whether in the privilege of listening to the stories of those I encounter, admiring the beauty of creation, the moments of solitude and silence, and everything in between. When I slow down and notice, life becomes a space of encounter, often leaving me in awe of its marvels. It is here that I encounter Truth Himself; where I catch glimpses of His infinite goodness.
And so, I desire to share the Gospel in ways that are rooted in real, lived experience - honest about the questions, struggles, hopes, and joys that shape our daily lives. I believe that within these moments lie deep truth, beauty, and goodness, all of which point us back to our Lord Jesus.
Through creative, thoughtful, and genuine communication, my hope is to help others recognise Christ’s presence in their own stories and encounter His love in all that is true, good, and beautiful.



Rachel Chan
I hereby command you: Be strong and courageous; do not be frightened or dismayed, for the Lord your God is with you wherever you go.
- Joshua 1:9
I plan and manage evangelisation events by coordinating end-to-end event operations. Through strong coordination and operational excellence, I help translate the Church’s evangelising vision into engaging, life-giving experiences for the Catholic community in Singapore.
After university, I joined an events agency and was soon traveling the world, managing high-profile projects, and growing in my career. I loved the excitement and recognition, but over time, I realized that success alone couldn’t fulfill me. My work had begun to consume my life, and I knew I needed a change.
Through it all, my faith and church community kept me grounded. I learned to listen, trust God, and step into the unknown. In 2024, I joined the ONE as an events executive. Today, I use my skills to create meaningful experiences for parishes, ministries, and everyday Catholics. This journey has taught me that true fulfillment comes not from accolades or travel, but from purpose, balance, and serving where God calls. I now go home after work each day joyful, energized, and at peace — grateful for the chance to live a life aligned with my faith and passion.



Emmanuel Ng
What, then, will anyone gain by winning the whole world and forfeiting his life? Or what can anyone offer in exchange for his life?
- Matthew 16:26
As part of ONE's Engagement team, I help parishes to inspire Catholics to be missionary disciples and to be witnesses for Christ. I also implement strategies to build our Service Team which seeks to facilitate the running of ONE's events and initiatives.
Spending more than 20 years in ministry work through Secondary Catechism and Altar Servers, my faith in Christ grew as I witnessed how Jesus touched the lives of others. Experiencing community within ministry helped me to understand more about what it meant to give myself fully in service to His will and calling. Seeing youth grow in faith and love allowed me to know more about how much God loved me.
After doing stakeholder engagement and volunteer management in the social services sector as well as working in mass communication, it is a blessing to be part of the mission to help people and parishes to become living witnesses for Christ through communion, mission and evangelisation. I pray that Christ will use me as His broken vessel to do His will.

“Jesus is the one needful thing - and the sufficiency of everything.”
(cf. Luke 10:42)
I help lead the lay apostolate by forming everyday Catholics to live their faith where they are - at home, at work, and in society. My work creates language and pathways for ordinary people to discover their vocation as everyday saints and witnesses of Christ in the world.
I am on this mission because I discovered myself first as the beloved of the Father, drawn into the life of the Son through the Spirit. From this intimacy, I began to recognise Jesus abiding in ordinary life. Growing up in a broken family, I first encountered Him in the Church, and it was in marriage and family life that His love slowly healed and reshaped me. I once thought holiness belonged mainly to sacred spaces. Over time, I discovered that Christ dwells in daily work, fragile relationships, and quiet acts of faithfulness. My calling is to help Catholics recognise their ordinary lives as holy ground, and to walk with them as they learn to live from Christ and make the Father’s Kingdom present wherever they are.



Sheila Fong
"I have loved you with an everlasting Love."
- Jer 31:3
Together with a team of volunteers, I journey with and form parish youth leaders across parishes, strengthening them for their evangelising work.
At 15, I encountered the immense love of God the Father in the Blessed Sacrament, a love beyond anything I had known. For the next 20 years, I longed for other young people to experience the same. Today, I seek to form and support leaders who can carry this mission forward, leading more youths to Jesus Christ.

OUR COLLABORATORS
The Office for the New Evangelisation is committed to building a ministry of collaborators to facilitate initiatives to move baptised Catholics into becoming missionary disciples, where collaborators become instruments of God's love to share Jesus with those they encounter.
ONE's Mission for Its Collaborators
Working Together to Become Missionary Disciples for Christ
- As laity, our duty is to become witnesses for the Gospel and sharing about Jesus with everyone we encounter - being missionary and evangelising.
- Our collaborators help us in this mission for the Archdiocese of Singapore.
Offering Spiritual Formation and Development Opportunities
- Formation is a lifelong process that is necessary for all laity.
- We are committed to helping our collaborators build the necessary charisms to help them become better witnesses for Christ.
Building A Ministry For Mission and Evangelisation
- The laity are called towards holiness - growing in faith with God; and communion - growing as the body of Christ.
- We are committed to growing our collaborators in holiness and communion, as brothers and sisters in Christ.
What We Hope For Our Collaborators
As we build our ministry of collaborators, we hope that they can serve through various gifts and charisms, including:
- Events (e.g. Registration, Ushering, Logistics, Group Facilitation, Scribes)
- Writers (creating content for Publications, Social Media etc.)
- Communications (Social Media, Website, Publicity)
- Designers
- Photographers
- Videographers
and more - we pray that all of our collaborators can use their gifts for service for love of Christ and others.
Our Formation:
ONE's first calling for our collaborators is to be missionary disciples for Christ in their daily lives. We are in the midst of setting up our formation process, for our collaborators to receive formation on a regular basis and equip them to be witnesses for Christ. More details will be released when they are finalised.
How to Apply?

Our Engagement staff will then reach out to you with the Application form, and will subsequently schedule an online meeting with you to get to know you better.



The Need for Formation - Open to All Catholics!
ONE will be conducting formation for all Catholics who are interested in being formed to become disciples for Christ. Find out more here!
WHO IS THIS FOR?
Are you:
- A new Catholic that is looking to understand more about the faith?
- A returning Catholic seeking to grow your relationship with Christ?

- Interested in knowing more about how we are called to be witnesses for Christ?

What We Are Moving Towards
Our formation sessions seek to inspire and train all Catholics who attend our sessions to become witnesses for the Gospel and sharing about Jesus with everyone they encounter - to become missionary disciples.
In virtue of their baptism, all members of the People of God have become missionary disciples (Evangelii Gaudium #120).
A missionary disciple is someone who fully lives out their baptismal calling:
- Holiness - Growing in faith in God and becoming Christ-like
- Communion - Being a participative member of the Body of Christ
- Mission - Joining Jesus in His mission
All are welcome!
Details
As we are in the midst of planning the formation pathways, details will be released when they are confirmed.

Our Collaborators
Our formation sessions also seek to increase awareness of ONE's initiatives and events that also work towards:
- Facilitate the revitalisation of parishes in becoming disciple-making and evangelising parishes
- Strengthen the spirit of communion among the Archdiocesan organisations to realise the Archdiocese vision.
For those who attend our formation sessions and are looking for ways to serve - they can join us as our collaborators, using their gifts and charisms for service out of the love of Christ. Do check out our collaborator positions for more information.
