Church father conundrum?

Based on the below statement, which passages (if any) *teach the trinity* without resorting to conjecture, inference, speculation or imagination? > The **Apostles** are not called **Church Fathers** because they don't teach the Trinity. That's utterly false. – eques https://christianity.stackexchange.com/questions/80602/why-arent-the-apostles-called-the-church-fathers **By my logic, eques means that the Apostles *do* teach the Trinity.** Should any passages/verses be provided, they should not form contradictions with other scripture - based on the belief that God does not contradict Himself. For example, 1 Cor 8:6, John 17:3 where God and or Jesus are defined as God or not God. Of course there are innumerably more like these but that is not the focus here. The conundrum being: Do the Church Fathers use any biblical references to support their theories that are literally taught by the Apostles?
