@Tes yeux noirs,
Technically. based on Jesus words at Matthew 5:32, the only basis for divorce that God recognises is adultery, meaning that anyone who divorces his wife on any other grounds, and marries another, this union isn't recognised by God, meaning that any sexual activity that follows is considered adultery. So the basis for the archbishops comments aren't exceptionally inaccurate. If however a man or woman are victims of infidelity, they may divorce and remarry with Gods approval, in which case they may fraternise like bunnies with no penalty
This is only really important to those who submit themselves to the authority of this God.
