Gennadius. Lives of Illustrious Men 27

Ursinus the monk wrote against those who say that heretics should be rebaptized, teaching that it is not legitimate nor honouring God, that those should be rebaptized who have been baptized either in the name of Christ alone or in the name of the Father and of the Son and of the Holy Spirit, though the formula has been used in a vitiated sense. He considers that after the simple confession of the Holy Trinity and of Christ, the imposition of the hands of the catholic priest is sufficient for salvation.
