If you want to argue on this, argue with the NT grammarians J. Gresham Machen, W. E. Vine, William Mounce, H. E. Dana, Julius R. Mantey, Walter Jerry Clarke, John H. Dobson, and Daniel B. Wallace, all of whose textbooks I have and study from; as well as J. Weingreen for Classical Hebrew. I also possess interlinear texts for both OT and NT, as well as the commonly used Strong's Exhaustive Concordance with Hebrew and Greek, Young's Concordance, Marvin Vincent's three volumes of Word Studies in the New Testament, Thayer's Greek-English Lexicon, Gesenius' Hebrew & Chaldee Lexicon, as well as a quite useful raft of Bible software from Logos and e-Sword, and access to anything generally available on the internet.
In this matter, I have just correctly directed you, guided by the inspired Words of the Holy Ghost as revealed by consummate translators of the King James Bible, masters in classical Greek, Hebrew, Aramaic, and the cognate languages, with reference in picayune issues to the Textus Receptus of Desiderius Erasmus and modified by Scrivener, published by the Trinitarian Society.
I also have the United Bible Society's Critical New Testament Greek Text, as well as a big, fat compilation of the Byzantine/Majority Textform with complete page-by-page verb parsing by Maurice A. Robinson and William G. Pierpont.
My discipler of some 25 years has been the author, pastor, missionary, and Bible translator Fred Wittman, whose volume 'The Gospels -- A Precise Translation' (click here) is freely available. My resource for difficult nuanced passages is a local pastor who is now finishing his doctoral sivinity thesis, a fine Greek and Hebrew instructor. For a pastime, he is currently memorizing Psalm 119 word for word--in the Hebrew.
Now, I'm not going to play the game of "my credentials are better than your credentials" with you, so you can stop now on that approach.
But there's nothing quite like being in complete agreement with the unimpeachable credentials of the plenarily and verbally inspired, inerrant, preserved Word of The God, which confounds your theory of the foundation of Christ's Church resting on any single disciple of Jesus and not on Jesus Himself.
Although it may be you have been persuaded that the Roman Catholic Church is founded on the person and work of Simon "Kephas" bar Jonah, it is Jesus Christ's Church which is in union with Him only in Heaven (Heb. 12:22-23), invisible to us; not the--at this time imperfect--leavened, visible institute(s) on earth.
I do not trust the Vatican-based worldwide religious organization as being a valid, reliable authority on expounding the Biblical Texts, inasmuch as it places itself over the Word as the final authority on how God deals with man, rather than God's Word being in authority over the earthly churches in every respect, with its commandments manifold, detailed, and explicit to any spiritually mature disciple of Christ.
The carnal mind is not subject to ... satan is the most clever attorney ever created, and he can divert a carnal mind onto numerous dead-end tracks. We post for the silent readers. Some on these threads will refuse to hear the Gospel of Grace no matter how many times it is offered, their pride will not allow them to see the Truth.
Yet you spent many words that seem to me centered on that effort and are essentially left with some coursework in German and the work of others.
The debate over Petros/Petra would have been solved had the extant text translated as:
You are an insignificant pebble, but on the profession of your faith I will build my Church; but it will be overcome for 1500 years until cometh the antisemite, the lawyer, and the adulterer. They will hate those who hold you in such high esteem as to think I could use you as the Apostle in the foundation of My Church, with Me as the chief cornerstone. I tell you ahead of time so people will not be confused and deceived for a thousand and half a thousand years. They will reform it into many branches, and continually reform and recreate it in the image of their minds; they and their followers, until the end. It will never be one until I return to judge everyone. Study the Greek ..,
There is no translation like that. We are left with the Greek, Aramaic, Hebrew, history, faith, and the Holy Spirit. If you are a convinced Baptist Brider, follow your conscience. Otherwise your faith community is from the reformation.
