pointing to himself? Is that actually in the verse in the Bible you have?
Ah, no. Just a Church tradition.
There is nothing in that verse that indicates that Jesus is speaking to or speaking of anyone but Peter.
There is certainly nothing in that verse that indicates that Jesus is pointing to himself, speaking to himself or speaking of himself.
In fact, no where in that passage or in any of the preceding or succeeding verses does Jesus refer to himself as rock.
If that is the tradition of your church, there is a serious disconnect between the actual words of Jesus and what this particular “church” wishes to believe.
