St.C: "Let's see, should I depend on the church that is the bride of Christ..."?
True Christians depend on the Holy Spirit.
The "Bride of Christ" is constituted of regenerate individuals in whom is the Holy Spirit. They make up the body of believers called "the church".
They are the ones to whom Jesus was speaking when he said: "I will pray the Father, and He will give you another Helper that He may abide with you forever, even the Spirit of TRUTH which the world cannot receive because it neither sees Him nor knows Him; but you know Him, for He dwells with you and shall be in you. ...the Holy Spirit whom the Father will send in My name HE will teach you....".
A true Christian would definately NOT want to depend upon those who infer that Jesus didn't mean what he said. Those people are denounced by the apostle John as "deceivers". As the apostle John said -- deceivers will try to tell him that he needs an *interpreter* other than the indwelling Holy Spirit to teach him.
John said to the individuals that make up the Bride of Christ: "The anointing which you have received from Him abides in you, and you do not need that ANYONE teach you ...".
St.C: "Your whole system rests on what I would describe as a faulty interpretation of 2 Tim;3:16. ..."
Who interprets 2Tim:3:16 for you?
It is the Spirit, not the pope, that dwells in every true believer's heart, who guides, teaches and abides with the church forever. For only the Spirit reveals the infinite wisdom of God and it is he who has given the church the written Word of God, the Holy Bible, to sanctify the church until Christ’s return:
"But the Comforter, which is the Holy Ghost, whom the Father will send in my name, HE shall teach you all things...” John 14:26
"How be it when he, the Spirit of Truth is come, HE will guide you into all truth...” John 16:13
"And I will pray to the Father, and he shall give you another Comforter, that HE may abide with you forever" John 14:16
"For what man knoweth the things of man save the spirit of man which is in him? Even so the things of God knoweth no man, but the Spirit of God.” 1 Cor 2:11
Since the whole sentence hinges on the word useful, Webster's Dictionary has had a part to play. Since the RCC doesn't seem to feel it needs to twist the meanings of words, my confidence in their interpretation is greater than those who would inject arbitrary definitions. Or does the Holy Spirit or "the mind of Christ" have trouble with the written word.
John 14:26 would appear to contradict sola scriptura, but I'm sure you have an explanation.
