11 For with respect to Trophimus also, of whom you wished tidings to be written to you, the case is not as the report and the falsehood of malignant people had conveyed it to you. For, as our predecessors often did, our dearest brother, in bringing together the brethren, yielded to necessity; and since a very large part of the people had withdrawn with Trophimus, now when Trophimus returned to the Church, and atoned for, and with the penitence of prayer confessed his former error, and with perfect humility and satisfaction recalled the brotherhood whom he had lately taken away, his prayers were heard; and not only Trophimus, but a very great number of brethren who had been with Trophimus, were admitted into the Church of the Lord, who would not all have returned to the Church unless they had come in Trophimus' company.
Therefore the matter being considered there with several colleagues, Trophimus was received, for whom the return of the brethren and salvation restored to many made atonement. Yet Trophimus was admitted in such a manner as only to communicate as a layman, not, according to the information given to you by the letters of the malignants, in such a way as to assume the place of a priest.
