Polycarp affirms the trinity.1 This is relevant because Polycarp's teachings matched that of the apostles.

Irenaeus (writing in c. AD 180): “The blessed apostles, then, having founded and built up the Church, committed into the hands of Linus the office of the episcopate. Of this Linus, Paul makes mention in the Epistles to Timothy. To him succeeded Anacletus; and after him, in the third place from the apostles, Clement was allotted the bishopric. This man, as he had seen the blessed apostles, and had been conversant with them, might be said to have the preaching of the apostles still echoing [in his ears], and their traditions before his eyes. Nor was he alone [in this], for there were many still remaining who had received instructions from the apostles. In the time of this Clement, no small dissension having occurred among the brethren at Corinth, the church in Rome despatched a most powerful letter to the Corinthians, exhorting them to peace, renewing their faith, and declaring the tradition which it had lately received from the apostles, proclaiming the one God, omnipotent, the Maker of heaven and earth, the Creator of man […][Against Heresies, Vol. 3, Ch. 3] • Clement was bishop of Rome. This is relevant because this is unlikely if Clement did not know the apostles.
• The Clement in Phillippians is Clement of Rome.2 This is relevant because it indicates Clement's teachings matched Paul's (who wrote Phillipians), and this in turn is relevant because Paul's teachings matched the apostles. The reason to think the Clement in Phillians is the Clement of Rome is the following.
“As Nero belonged to the Claudian family, and his consort Messalina to the Valerian, several instances have been found of the two names Claudius (or Claudia) and Valerius (or Valeria) occurring in combination with reference to servants in the royal employment. Possibly this is the case here. It has even been conjectured that these two elderly envoys may have been among the members of 'Caesar's household' mentioned by St Paul in Philippians iv, 22.”
• Clement in Phillipians is associated with members of Caesar's household (Philippians 4:22 “All the saints greet you, especially those of Caesar's household.”)
