The Word of Yahuweh can't be any plainer than this.
The Savior for whom the Rock was named, asked His disciples the most important question ever posed: "Who do you say (lego - affirm and maintain, advise and teach) I Am (eimi - I exist and am present as)?" To which, a disciple named for the astuteness of his revelation, responded: "Simon (a transliteration of the Hebrew name Shimown, meaning to listen, understand, discern, regard, and proclaim) Petros (a masculine proper name meaning pebble or stone) gave the answer, The Messiah, the Son of the living God." (Matthew 16:15-16)
Affirming this live-saving truth, "Yahushua said (lego), Blessed (makarios - a poetic term denoting transcendent happiness in a life beyond labor and death) are you Shimown (the one who listens, understands, discerns, regards, and proclaims), son of (bar) Yonah (from yownah, meaning the dove; the name of a Yahudi sent to Nineveh, Assyria whose life and book serve as a prophetic metaphor for Yahushua saving Gentiles), because flesh and blood did not make this manifest (apokalupto - disclose by baring), but My Father who is in Heaven." (Matthew 16:17) As is usually true with Scripture, every name and nuance was carefully chosen, revealing subtle and profound truths.
What follows is important. Petros/Peter isnt the petra/bedrock. The recognition that "Yahushua is the Messiah, the Son of the living God," is the foundation upon which the ekklesia/called-out assembly would be restored and established. Beyond the evidence sprinkled throughout the Tanach, identifying the Rock with Yahshua, "Petros" was a man and every reference to "petra/bedrock" is feminine.
"Indeed (de), I (kago) say (logos) concerning this (hoti - as a marker of equivalence for identifying and explaining this) to you (soi), you (su) are (ei) Petros (a masculine proper noun meaning pebble or stone), and (kai) upon/by/in/with (epi - "upon" when used with things that are at rest, "by" when used in relationship to people, "with" when used in connection with authority, and "in" used in reference to an observation) this one (taute - singular feminine demonstrative pronoun) Rock (petra - bedrock, a feminine noun; a large stone which projects itself) I shall build by edifying, promoting, and restoring (oikodomeo - rebuild and establish, strengthen and enable, instruct and improve) My (mou) called out gathering (ekklesia)." (Matthew 16:18)
English translations all leave "hoti/concerning this" out of their renderings of Yahshuas answer. Had it been included, no rational person would have thought that Petros, rather than his answer, was the foundation of the ekklesia. The source of edification and restoration is the Savior, not his flawed and imperfect disciple.
Believing Peter is the Rock is irrational and delusional. The evidence of Yahuweh's Word is irrevocable/irrefutable and supercedes, trumps, pre-empts, negates, refutes, and proves to be a lie all that oppose/contradict it, whether said opposition is human or church dogma.
