João 4

João 4:44

If any brother, man or woman, come in from another parish, bringing recommendatory letters, let the deacon be the judge of that affair, inquiring whether they be of the faithful, and of the Church? whether they be not defiled by heresy? and besides, whether the party be a married woman or a widow? And when he is satisfied in these questions, that they are really of the faithful, and of the same sentiments in the things of the Lord, let him conduct every one to the place proper for him. And if a presbyter comes from another parish, let him be received to communion by the presbyters; if a deacon, by the deacons; if a bishop, let him sit with the bishop, and be allowed the same honour with himself; and thou, O bishop, shalt desire him to speak to the people words of instruction: for the exhortation and admonition of strangers is very acceptable, and exceeding profitable. For, as the Scripture says, "no prophet is accepted in his own country." Thou shalt also permit him to offer the Eucharist; but if, out of reverence to thee, and as a wise man, to preserve the honour belonging to thee, he will not offer, at least thou shalt compel him to give the blessing to the people. — Constitutions of the Holy Apostles Book 2
