Canons of Local Councils Received in Trullo (Sardica, Carthage) · The Seven Holy Ecumenical Councils
Bishop Hosius said: This is the sentence of my mediocrity [i.e., unworthiness]—that, since we ought to be gentle and patient and to be constant in compassion towards all, those who were once advanced to clerical office in the Church by certain of our brethren, if they are not willing to return to the churches to which they were nominated [or, espoused], should for the future not be received, and that neither Eutychianus should continue to vindicate to himself the name of bishop, nor yet that Musæus be accounted a bishop; but that if they should seek for lay communion, it should not be denied them.
LocalT 1.23.3
A clergyman who does not live in the Church among whose clergy he is enrolled should not be received. Eutychian and Musæus shall not have the name of bishops. But let them be admitted to communion with the laity, if they wish.
