Archbishop Justin Welby will be joined with the head of the Catholic Church in England and Wales, Cardinal Vincent Nichols for a live chat on Facebook.
The Archbishop of Westminster will join Justin Welby on Friday to discuss "prayer, unity and sharing the good news of Jesus Christ", according to the Facebook event.
The Church leaders have invited Facebook users to ask live questions on the video, which is set to air at 2.20pm.
Questions so far include "Will the church rejoin the Catholic communion?" and "What are churches doing to ensure that young people are properly discipled?".
Cardinal Nichols told the Tablet that the initiative "goes to demonstrate the level of our cooperation and partnership."
The ecumenical event shows "what it means to pray together as Anglicans and Catholics", a spokesperson from Lambeth Palace told the Tablet.
Welby hosted a live Bible study on his Facebook page last Thursday, which has been viewd more than 885,000 times.
Nichols and Welby have shared a platform before when they were interviewed by Nicky Gumbel at the HTB Leadership Conference.
Welby spoke of the "implicit trust" present in their friendship.
"It is not something that is heavy, that we work at because it's an uphill struggle, but it's much more like a breeze coming from behind us that catches our sails and helps us to go forward."
Nichols said that reconciliation was "not something we negotiate and construct, but something we receive in two places: on our knees and in the service of the poor."
