“Christ/God IS Truth. There is a difference.”
So, Christ is truth, and the church, according to you, is the foundation of truth, therefore the church is the foundation of Christ. Instead, the Bible says Christ is the chief cornerstone of the church. Your alternate blueprint would be quite unfeasible.
You err in what the Church is, to begin with. It is the body of Christ. Christ is the head.
Now review your theology with this in mind.
And you still have the problem of Holy Scripture not agreeing with your interpretation:
“thou mayest know how thou oughtest to behave thyself in the house of God, which is the church of the living God, the pillar and ground of the truth.”
