Most Rev Justin Welby has asked churches from across the country to unite and "pray together for more people to know Jesus Christ" for the ten days before Pentecost on Sunday 4th June 2017.
The Presidents of Churches Together in England have jointly announced they are inviting churches to pray "intensively and intentionally" that more people will come to the faith.
The aims of prayer:
- to join with the whole family of God the Father
- to pray for the empowering of God the Holy Spirit
- that we may be effective witnesses to God the Son Jesus Christ
The group includes the leader of Catholics in England and Wales, Cardinal Vincent Nichols, Rev Dr Hugh Osgood, the Free Churches Moderator and Archbishop Gregorios, the President for the Orthodox Churches.
A statement from the group said: "We want to encourage our brothers and sisters in churches of all traditions to partner in praying 'Thy Kingdom Come' in the days leading up to Pentecost, from 25 May - 4 June, 2017.
"There is no prescription about how we should pray; we hope each church will participate in a way that is authentic to them and where possible to engage in this with their partner churches in their area."
The request comes after the success of Thy Kingdom Come in 2016 where around a hundred thousand Christians joined together in prayer across England.
Archbishop Justin Welby, said: "It was profoundly moving to see over a hundred thousand people around England and beyond praying together during Thy Kingdom Come in the ten days before Pentecost this year.
"As we look ahead to 2017 there is growing desire, as beautiful as it is remarkable, among people of so many denominations and nations to pray together for more people to know Jesus Christ.
"I pray that Christians everywhere say yes to this movement of the Spirit, and come together as one in prayer."
