Augustine was the originator of a number of alien beliefs that have infiltrated the Church. Thankfully, there are copious writings prior to him from church leaders that provides a pretty clear portrait of what the disciples of the apostles thought of foreign ideas to the faith for the first two centuries after the Resurrection.
This is one of the best articles I've found on the topic.

Jesus would vindicate—or prove right and just—his Father’s sovereignty, or way of ruling."
This is the lame excuse that the Watchtower gives for Jesus Sacrifice NOT the personal payment for your sin.
The biblical concept is a simple one. The wages of sin is death. So, Jesus offers to make that payment on your behalf so that God can be perfectly justified in giving you a resurrection.... Which he desires to do.
2 Corinthians 5:21
He made Him who knew no sin to be sin on our behalf,
so that we might become the righteousness of God in Him.
This is the exchange, or transaction if you will contained in the New Covenant.
Galatians 3:13
Christ redeemed us from the curse of the Law, having become
a curse for us--for it is written, "CURSED IS EVERYONE
WHO HANGS ON A TREE"
The believer willingly trades places with Jesus. Agreeing with the punishment for sin.
Galatians 2: 20
I am crucified with Christ: nevertheless I live; yet not I, but Christ lives in me:
Jesus displayed publicly the amazing power he possessed as the Source of Life. When anything is separated from this Life, decay is the result.
Jesus offered escape from decay by allowing the Holy Spirit to operate in a person from the inside. The believer concedes his absolute authority over himself to God, and as a result is reconnected to the Life Source. Being Justified, he owns a permanent right to life..... not just a gift only.
"whom He called, these He also justified; and whom He justified, these He also glorified."
