During a press conference in Canterbury on Tuesday, GAFCON spokesman Rev Andrew Gross said some Primates will ask that the Scottish Episcopal Church be required to repent for its decision to let clergy conduct same sex weddings last June.
Rev Andrew said if there's no repentance "I'm not sure if they can remain in the room" but he said it's up to the conscience of the individual Primate on what their reaction is.
He warned against "punitive sanctions" for the SEC like those that were taken against The Episcopal Church in the United States (TEC) in January 2016.
The Anglican Communion decided not to remove the TEC from the group after its decision to allow same-sex marriages. It limited their role in the Communion for three years instead.
Gross said the SEC must submit to God's truth, seek forgiveness and work toward restoring its relationship with the Church in order for any sanctions to be effective.
The Archbishops of Nigeria, Rwanda and Uganda refused to attend this week's Anglican Primates' Meeting over what they deem as a weak stance on the issue of sexuality in the Church.
Possible sanctions for the SEC are expected to be announced on Tuesday evening.
