According to the account of Irenaeus ( and ), Cerdo had not the intention of founding a sect apart from the church. He describes him as more than once coming to the church and making public confession, and so going on, now teaching his doctrine in secret, now again making public confession, now convicted in respect of his evil teaching, and removed from the communion of the brethren ("aphistamenos tes ton adelphon synodias"). Some understand this to mean that Cerdo voluntarily withdrew himself from communion, but it is preferred to understand the word passively, with the old translator of Irenaeus, "abstentus est a religiosorum hominum conventu."
