Felix (26) I. , bp. of Aptunga, in proconsular Africa. Felix was one of those who laid hands on Caecilian as bp. of Carthage, if not the sole officiating bishop, a.d. 311 (Aug. Brevie. Coll. iii. 14, 26; 16, 29). The Donatist party, having failed in the Court of Inquiry at Rome, under Melchiades, Oct. 2, 313, to establish their case against Caecilian, turned their attack on Felix, whom they sought to convict of the infamous crime of "tradition" in the persecution of Maximus, a.d. 303. The emperor gave orders to Aelianus, the proconsul of Africa, to hold an inquiry on the spot, which took place on Feb. 15, 314 (Aug. Post. Coll. 38, 56; Ep. 43, 3-14; 88; c. Cresc. iii. 61) at Carthage, in the presence of many who had held municipal offices at the time of the persecution. In vain the prosecution relied on a chain of fraudulent evidence elaborately concocted. The proconsul pronounced the complete acquittal of Felix, which was confirmed by the emperor, and repeated in a letter to Verinus, or Valerius, the vicar of Africa, a.d. 321. The whole case was brought up again at Carth. Conf., a.d. 411, when Augustine argued that there was no doubt of the completeness of the imperial decision. Aug. c. Cresc. iii. 81, iv. 79; de Unic.
