That isn't true either. You claim....
You are making a fundemental error! You are confusing what people "claim" with what Scriptures teach. The scriptures clearly teach that the Holy Spirit is the teacher of truth - 1 Jn. 2:29. It does not matter what a person may claim. The truth is not changed because their claim is true or false.
Instead you are playing the divide and conquer card based upon a purely fabricated straw man argument!
The "church" is the "pillar and ground of the truth" but it is not the Roman Catholic Church which is the pillar and ground of paganized Christianity. The church of 1 Timothy 3:15 is the same in nature that qualfies a Bishop and deacons as described in 1 Tim. 3:1-13 and administers the ordinances and preaches the gospel of justification by grace alone through faith alone in Christ alone without works evidenced by the fruits of regeneration - "good works."
