So, Pon de Replay, you now believe in God, but that after creation, He just abandoned the whole thing and doesn't get involved?
This will sound like semantics, but I don't believe that with any certainty, no. It's possible such a scenario is true, but I don't know or believe it to be true. What you have articulated appears to be deism, but accepting the proofs for an Uncaused Cause does not rule out monism or pantheism. It could be the case that, far from abandoning creation, God sustains creation at every successive moment. Or, being fallible, I could be in error in accepting the Uncaused Cause. There could somehow be an infinite regress of cause and effect which goes beyond my mortal understanding.
I also don't rule out the possibility of an interventionist God. It might be true that God sometimes intervenes and other times withdraws, we know not why, only that it must be according to his design. Or some would say that God's interventions are synonymous with everything that occurs: "I form the light and create the darkness, I make weal and create woe; I, the LORD, do all these things." Each of these positions refutes the other, and at present I have no means of confirming or positively denying any of them. All I can do is ascribe likelihood. Monism is probably the highest on my likelihood scale, but I treat it as a hypothesis and not a belief.
You seem to care for REASON, as you participate in it yourself. What becomes of reason when in Scripture things like this were predicted, and ever since then have been fulfilled in every age, only in Catholicism?
"Believe you not that I am in the Father, and the Father in me? Otherwise
believe for the very works' sake. Amen, amen I say to you, he that believeth
in me, the works that I do, he also shall do; and greater than these shall
he do" (John 14:11,12)
"And going, preach, saying: The kingdom of heaven is at hand. Heal the sick,
raise the dead, cleanse the lepers, cast out devils: freely have you
received, freely give" (Matt. 10:7,8)
"And these signs shall follow them that believe: In my name they shall cast
out devils: they shall speak with new tongues. They shall take up serpents;
and if they shall drink any deadly thing, it shall not hurt them: they shall
lay their hands upon the sick, and they shall recover... But they going
forth preached everywhere: the Lord working withal, and confirming the word
with signs that followed." (Mark 16:18,20)
