As a loyal son of the Church, I, too support the Fourth Lateran.
I reject the claims of the messiahhood and the divinity of Jesus because I read the Hebrew scriptures as a Jew. Jesus did not fulfil the messianic prophecies, and God is a unity, not a trinity. The rest is detail.
With all due respect: you are wrong. But instead of arguing with you, I'll just remember you in my prayers. If you seek, you will find; if you look, you will see. May Christ help you to seek and look. "Resplendent and unfading is Wisdom, and she is readily perceived by those who love her, and found by those who seek her." [Wis. 6:12]
No, you are wrong. The difference is, I don't feel compelled to try to convert you to my beliefs.
But instead of arguing with you, I'll just remember you in my prayers.
Prayers are always welcome. I'd just ask that you pray for God's will for me, rather than specifically for my conversion.
