I would agree with this statement completely. Jesus is the cornerstone of our faith. The corner stone is what holds a building together… the most important stone there is
Cornerstone
- a stone uniting two masonry walls at an intersection. 2. a stone
representing the nominal starting place in the construction of a
monumental building, usually carved with the date and laid with
appropriate ceremonies. 3. something that is essential, indispensable,
or basic 4. the chief foundation on which something is constructed or
developed
This doesn’t negate Peter being the rock on which the Church is to be built. A rock and a cornerstone are two complete different things.
The rock is a foundation, the strength, but the cornerstone is the main representation of that strength… what everyone sees and what everyone focuses on. We as a rule don’t focus on what a building is built upon, even though it’s extremely important to have firm ground, but we sure do see the cornerstone.
Jesus is the cornerstone, He is the one whom we celebrate, whom we focus on, who is the whole strength of the Church.
