[daniel1212]

Just as the Apostles did not use the words "Incarnation" or "Trinity" nor make a verbal distinction between Christ's Person and His nature --- but knew, certainly after the Resurrection, that He is both "Lord" and "God" --- as Thomas said.

You simply cannot make something like the Assumption of Mary nor praying to her analogous to the Trinity! The former is so lacking on warrant from Scripture or early history that Rome's own scholars opposed it being taught as part of apostolic tradition. Meanwhile Scripture nowhere testifies to believers praying to anyone else in Heaven but the Lord, despite prayer being so basic a practice that the Spirit provides approx. 200 prayers in Scripture! And there were plenty of angels for OT believers to pray to, as well as a multitude of ascended believers in Heaven for the NT church to make supplication to. Spare us the refuted attempts at egregious extrapolation: it simply is not there and its absence is inexplicable for a most basic practice, while making supplication to invisible created beings in the Heavens is recorded - by pagans.

In contrast the Trinity is a demanded doctrine in the light of the abundant testimony to Christ being God in nature with the Father, and with the Spirit.

I don't go beyond what it says in Munificentissimus Deus. There was evidence requiring an explanation. The explanation was proclaimed in the encyclical.
