Thank you, Kay! I used to believe in the Catholic trinity I heard but, if you don't mind this simple idea I will leave: At the cross I see two things happening. GOD, who dwelt in Jesus' body-TEMPLE left Him alone in that cross that now saves us. That was the moment Our Lord and Savior Jesus quoted Psal 22.
So, to my dull understanding, GOD "died" leaving Jesus body alone in His cross. Later on, few moments, the very Spirit of the Lord Jesus Christ died, leaving His own body; because dying is leaving the earthly body (and those cells die the medical way we probably know, from lack of oxygen, etc).
On the other hand, no one would die for misunderstanding the theory of the trinity (same way those who believe in the theory of the evolution, a thing i desbelive). I have believed GOD dwelt in Jesus body and, several times GOD spoke using Jesus' mouth and, if Jesus was God, our Father, how come would the devil have dared to test Him in the dessert?
Thank you again! I have spent years believing that way and, when i die, I hope this possible sin be forgiven too, because I'm tired of believing things "heard" and big truths, like these, GOD could help His people understand or believe, but no one will die for being dull... Just and example -the apostle Thomas- He had to see the resurrected LORD to believe He was alive and resurrected so, that one who spent more than 3 years with the Lord, who saw His miracles (and God's too) disbelieved the Good News (His Gospel) and this secular hermit rejects following things heard -and taught- by human traditions and Catholic lecturers.
Thank you for that kindness!
