"Q. 1196. Do we not slight God Himself by addressing our prayers to saints?
A. We do not slight God Himself by addressing our prayers to saints, but, on the contrary, show a greater respect for His majesty and sanctity, acknowledging, by our prayers to the saints, that we are unworthy to address Him for ourselves, and that we, therefore, ask His holy friends to obtain for us what we ourselves are not worthy to ask."
Actual scripture tells us the opposite however.
Mt 6:6
But thou, when thou prayest, enter into thy closet, and when thou hast shut thy door, pray to thy Father which is in secret; and thy Father which seeth in secret shall reward thee openly.
Lu 11:2
And he said unto them, When ye pray, say, Our Father which art in heaven, Hallowed be thy name. Thy kingdom come. Thy will be done, as in heaven, so in earth.
In these scriptures Christ taught us EXPLICITLY to pray to the Father. The only go-betweens the Bible ever speaks of in our prayers is Christ himself (as he tells us to ask the Father for things in Christ's name) and the Holy Spirit of which he says:
Ro 8:26
Likewise the Spirit also helpeth our infirmities: for we know not what we should pray for as we ought: but the Spirit itself maketh intercession for us with groanings which cannot be uttered.
Further human intervention is not at all necessary.
He burneth part thereof in the fire; with part thereof he eateth flesh; he roasteth roast, and is satisfied: yea, he warmeth himself, and saith, Aha, I am warm, I have seen the fire: And the residue thereof he maketh a god, even his graven image: he falleth down unto it, and worshippeth it, and prayeth unto it, and saith, Deliver me; for thou art my god. They have not known nor understood: for he hath shut their eyes, that they cannot see; and their hearts, that they cannot understand. And none considereth in his heart, neither is there knowledge nor understanding to say, I have burned part of it in the fire; yea, also I have baked bread upon the coals thereof; I have roasted flesh, and eaten it: and shall I make the residue thereof an abomination? shall I fall down to the stock of a tree? He feedeth on ashes: a deceived heart hath turned him aside, that he cannot deliver his soul, nor say, Is there not a lie in my right hand? " -- Isaiah 44:15-20"Then shall it be for a man to burn: for he will take thereof, and warm himself; yea, he kindleth it, and baketh bread; yea, he maketh a god, and worshippeth it; he maketh it a graven image, and falleth down thereto.
