The Trinity – the doctrine or teaching that God is Father/Creator, Son/Redeemer, and Holy Spirit/Sanctifier – is central to Catholicism. But no one fully understands the Trinity. That is why so few people ever talk about the Trinity; the focus is usually on one or another Person of the Trinity (the Father, or Jesus, or the Holy Spirit), rather than God as Triune (three in one).
