We can't do anything to bring about our salvation, not even get baptised. And so it goes on. The churches of Christendom have completely lost the Jewishness of Jesus' and apostle's teaching. They have become polytheistic pagan worhsippers. Palestrina, the Trinity is not easy to understand by even scholars.
Pastors have a hard time explaining it.
It is full of contradiction within itself and with the Bible. Yet somehow Trinitarians continue in this lie even when they are shown the truth.
