Plenary (against the Donatists) The Baptism of Heretics
Can. 8. Concerning the Africans, because they use their own law so as to rebaptize, it has been decided that, if anyone from a heretical sect come to the Church, he should be asked his creed, and if it is perceived that he has been baptized in the Father and the Son and the Holy Spirit, only the hand should be imposed upon him, in order that he may receive the Holy Spirit. But if upon being questioned he does not answer this Trinity, let him be baptized.
