Hi Mercuriel. With reference to the link that troubled you, right in the beginning, the mention of these two “fathers” is an error in itself.
Tertullian: Unlike many church fathers, he was never canonized as a saint because some of his teachings directly contradicted the teachings attributed to the apostles, notably the Apostles Paul and John.
**Origen: **He wrote his trinitarian formula after becoming a Montanist. (A heretical sect) However, unlike many Church Fathers, he was never recognized as a saint by the Church, as several of his later teachings directly contradicted the teachings of the Church.
**Eusebius: **(From your link) Eusebius unambiguously teaches that the rock is Christ. …] However he interprets this to mean that the Church is to be built upon the words or teachings of the apostles and prophets as opposed to their persons… It is in this sense that it can be said that the Church is built upon Peter and the other apostles.
Do you see the error here? An interpretation that intends to negate Catholic understanding and teaching. Maybe this is a good place to leave off pointing to the discrepancies in the article, and focus on Catholic truth instead.
Many threads and arguments are available all over this forum relating to the true interpretation, but I rather like this one. In the Old Covenant, we know that God Himself instituted the pattern and worship of the Israelite community, and this prefigured what would be the pattern in the New Covenant. Just as the Israelite community was built on the 12 tribes with Aaron as its priest, the new covenant people of God are built on the 12 apostles. However, one of these 12 were appointed to be Pope, i.e., Peter, as was Aaron.
We find solid identification of this primacy in Numbers, Chapters 16 and 17. Aaron was the only lawful authority appointed by God, yet others in the ranks (Korah and his schismatic band) contested this authority publicly, saying, "The whole community is holy, every one of them, and the Lord is with them. Why then do you set yourselves above the Lord’s assembly?”
Numbers 17: "The staff belonging to the man I choose will sprout, and I will rid myself of this constant grumbling against you by the Israelites.”
6 So Moses spoke to the Israelites, and their leaders gave him twelve staffs, one for the leader of each of their ancestral tribes, and Aaron’s staff was among them. 7 Moses placed the staffs before the Lord in the tent of the covenant law.
8 The next day Moses entered the tent and saw that Aaron’s staff, which represented the tribe of Levi, had not only sprouted but had budded, blossomed and produced almonds.10 The Lord said to Moses, “Put back Aaron’s staff in front of the ark of the covenant law, to be kept as a sign to the rebellious.
Numbers 18:7: “Only you (Aaron) and your sons (successors) are to have charge of the priestly functions. Anyone else who comes near must die.” (And Korah and his rebellious band were all killed in punishment for their audacity in assuming a call that was never theirs.)
Hebrews 5:4: "And no one can become a high priest simply because he wants such an honor. He must be called by God for this work, just as Aaron was.
May the Lord give you much light about this and remove your doubts. :gopray2:
