Canon 7
Who accepts someone excommunicated by others, should be excommunicated himself.
Felix, bishop of Selemsela, said: I also suggest to your sanctities that those who are expelled from the church because of their wrongdoings and would dare either to go to the imperial court, or to rush to civil courts, or if they may approach another Catholic church and a bishop or a cleric accepted them without the consent [of their bishop], what should be done about them?
Epigonius, bishop of Bulla [Regia], said: If a bishop of the Catholic communion encouraged such a man with false favours, he should know that he is as depraved as those rejected by the church, and that he shares their fate.
Bishop Geneclius said: our brothers and fellow bishops rightly suggest that if someone was expelled from the church because of his wrongdoings and was accepted into communion by any bishop or cleric, these latter will be held responsible for the same crime as was committed by the former.
And all bishops said: we all agree.
