Inaugurated in September 2013, the Office for the New Evangelisation (ONE) is part of The Titular Roman Catholic Archbishop of Singapore working to realise the Archdiocese vision of being a vibrant, evangelising and missionary church.


As a catalyst for the New Evangelisation, ONE’s mission is to facilitate processes and initiatives to move baptised Catholics into becoming missionary disciples.

Anchored upon the four tenets of Word, Worship, Communion and Witness, the office seeks to catalyse the New Evangelisation by advocating a change of culture and mindset, aligning the different Archdiocesan organisations, and providing resources and formation to realise the vision of a vibrant, evangelising and missionary church.


• Inspire and train all Catholics to become witnesses of the Gospel and sharing Jesus with everyone they encounter.
• Strengthen the spirit of communion among the Archdiocesan organisations to realise the Archdiocese vision.
• Facilitate the revitalisation of parishes in becoming disciple-making and evangelising parishes.
