Nicæa I: canon XIX

Concerning the former Paulinists who seek refuge in the catholic church, it is determined that they must be rebaptised unconditionally. Those who in the past have been enrolled among the clergy, if they appear to be blameless and irreproachable, are to be rebaptised and ordained by the bishop of the catholic church. But if on inquiry they are shown to be unsuitable, it is right that they should be deposed. Similarly with regard to deaconesses and all in general whose names have been included in the roll, the same form shall be observed. We refer to deaconesses who have been granted this status, for they do not receive any imposition of hands, so that they are in all respects to be numbered among the laity.
