No, I understand these scriptures, but that is not my understanding of scripture or the priests understanding of scripture. Our understanding of Scripture is 2000 year old Apostolic Tradition, The Tradition of The Holy Spirit.
We are meant to trust God with all our heart and trust not our own understanding as it states in scripture.
You think it’s normal to trust your own understanding, but it’s not biblical, that’s why Bible alone Protestantism has gone on to countless conflicting interpretations and doctrines.
Don’t do it.
Trust God, Trust The Tradition of The Holy Spirit.
The Holy Spirit inspired the scriptures and God has given man the ability to understand those same scriptures.
Understanding what the words of these verses mean is not difficult,
Mat 16:16 Simon Peter answered, "You are the Christ, the Son of the living God."
Mat 16:17 And Jesus said to him, "Blessed are you, Simon Barjona, because flesh and blood did not reveal this to you, but My Father who is in heaven.
Mat 16:18 "I also say to you that you are Peter,
G4074 and upon this rock
G4073 I will build My church; and the gates of Hades will not overpower it.
The testimony of who Christ is is the rock upon which the church is built. But the RCC has to hold to an errant view that Peter is the foundation in support of their false idea that he was the first pope and of your papal succession that is supposed make the RCC the "only true" church. But when the foundation of your church is based upon errant theology then why would one think the overall theology of the church would be any better.
The RCC has chosen to build itself on a man "Peter" rather than on God "Christ Jesus". As a result in it's vain attempt to justify itself it has brought many false teachings into your religion eg. Mary worship, transubstantiation, prugatory, Papal infallibility. All ideas that the RCC has foisted on the bible with no support.
You keep saying that Protestantism has gone on to countless conflicting interpretations and doctrines. I can not speak for other denominations or even for all Baptists. Speaking for myself as a Baptist I do not try to add or subtract from scripture but hold to a personal understanding of scripture as lead by the Holy Spirit.
What you have not addressed is the clear fact the the RCC has added to and subtracted from the text of scripture. You have placed your tradition over scripture and you will spend hours defending that.
