Christ/God IS Truth. There is a difference.
The Church is the pillar and foundation of all truth - as Holy Scripture says. You can’t get a ‘whom’ from a ‘which’ in your interpretation. And, that’s just for starters.
To assume "the church" is the one which has it's headquarters singularly in Rome --- is to assume wa-aay too much which is not established in scripture, or WAS the identification just what "the church" was, and was composed of, in the very earliest understandings and tradition of "the church", either.
“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.
Psa_115:15 Ye are blessed of the LORD which made heaven and earth.
You better go to the next one...That didn't work either...
