Under the draft legislation before the General Synod, a woman bishop would delegate to a stand-in male bishop to minister to an objector parish by reference to a code of practice.
The legislation has been backed by 42 out of the 44 Church of England dioceses but needs a two-thirds majority in all three houses of the General Synod - of bishops, clergy and laity - to gain final approval.
Commentators have said they believe it will clear the houses of bishops and clergy with the necessary two-thirds majority but the outcome among lay members of the General Synod is thought to be on a "knife-edge".
Anger is building in the Commons over the Church of England's decision on women bishops, but what action, if any, can be taken?
The Church of England General Synod voted against allowing women bishops in what the Archbishop of Canterbury called "a missed opportunity".
Today's debate on female bishops is painfully slow but shows the determination of the Church to build consensus and respect their community.
