The pillar and foundation are not the things that they are upholding.
This is what truth is.
John 14:6 Jesus said to him, I am the way, and the truth, and the life. No one comes to the Father except through me.
John 17:17 Sanctify them in the truth; your word is truth.
2 Timothy 2:15 Do your best to present yourself to God as one approved, a worker who has no need to be ashamed, rightly handling the word of truth.
Yeah, but you are ignoring the clear words of Scripture, that says the Church IS the pillar and foundation of Truth.
So I ask you again, WHICH Church is the pillar and foundation of truth? Be specific.
