CANON 4

Summary. Those baptized by the Latins must not be rebaptized by the Greeks.

Text. Though we wish to favor and honor the Greeks who in our days are returning to the obedience of the Apostolic See by permitting them to retain their customs and rites in so far as the interests of God allow us, in those things, however, that are a danger to souls and derogatory to ecclesiastical propriety, we neither wish nor ought to submit to them. After the Church of the Greeks with some of her accomplices and supporters had severed herself from the obedience of the Apostolic See, to such an extent did the Greeks begin hating the Latins that among other things which they impiously committed derogatory to the Latins was this, that when Latin priests had celebrated upon their altars, they would not offer the sacrifice upon those altars till the altars had first been washed, as if by this they had been defiled. Also, those baptized by the Latins the Greeks rashly presume to rebaptize, and even till now, as we understand, there are some who do not hesitate to do this. Desirous, therefore, of removing such scandal from the Church of God, and advised by the holy council, we strictly command that they do not presume to do such things in the future, but conform themselves as obedient children to the Holy Roman Church, their mother, that there may be "one fold and one shepherd." If anyone shall presume to act contrary to this, let him be excommunicated and deposed from every office and ecclesiastical benefice.
