1. Catholics do not regard saints as 'God' nor as demigods.
2. You are correct that God is jealous and wants us to have no God's except for Him. Now you just need to grasp that the Holy Spirit reveals Jesus to us as Lord and that it is perfectly fine to serve, worship and pray to Jesus as He is God the Son.
1 Cor 12:3 Therefore I want you to know that no one who is speaking by the Spirit of God says, “Jesus be cursed,” and no one can say, “Jesus is Lord,” except by the Holy Spirit.
If you do not know Jesus as Lord, from this verse one could argue that you don't know Jesus.
Regarding your verses in Matthew and Mark, you are making a common error of not grasping 'God in flesh'. Verses like this point to God truly placing Himself in flesh on our level. No ''cheating''.
We have had discussions on the trinity on this site, you can find one and discuss further there if you wish. They are lengthy and will derail this thread. I wished only for a short rational chat on it.
Hi Thanks. .
I would think Catholicism is the only Christian based religion that does seeks after patron saints, his and her disembodied gods .workers with a familiar (family spirit)
Same kind of communication used by Saul when the lord cut of or forms of communication.
Saul consulted a mystic or witch a mediator set between the things of this world and to unseen world.
When she performed the work of calling up the dead legion . She needed a description . Then Saul bowed down and worshiped the dirt
1 Samuel 28:7-25Then said Saul unto his servants, Seek me a woman that hath a
familiar spirit, that I may go to her, and enquire of her. And his servants said to him, Behold, there is a woman that hath a familiar spirit at Endor.And Saul disguised himself, and put on other raiment, and he went, and two men with him, and they came to the woman by night: and he said, I pray thee,
divine unto me by the
familiar spirit, and bring me
him up, whom I shall name unto thee.And the woman said unto him, Behold, thou knowest what Saul hath done, how he hath cut off those that have
familiar spirits, and the wizards, out of the land: wherefore then layest thou a snare for my life, to cause me to die?;And Saul sware to her by the Lord, saying, As the Lord liveth, there shall no punishment happen to thee for this thing.Then said the woman, Whom shall I bring up unto thee? And he said,
Bring me up Samuel.;And when the woman saw Samuel, she cried with a loud voice: and the woman spake to Saul, saying, Why hast thou deceived me? for thou art Saul.And the king said unto her, Be not afraid: for what sawest thou? And
the woman said unto Saul, I saw
gods ascending out of the earth.And he said unto her, What
form is he of? And she said, An old man cometh up; and he is covered with a mantle. And
Saul perceived that it was Samuel, and he stooped with his face to the
ground, and
bowed himself.
In that way be careful how we hear who we say we do .. except by the Holy Spirit working in the believer .
