As for the proper interpretation of the verse:
The "pillar" and "ground" of the truth --- the structure that upholds God's truth on earth --- is the Church of God.
Tagline.
EVERY assembly is responsible to do this.
Unfortunately, Rome doesn't teach the full scriptures, but a select portion that they hit over and over and over.
But it's not...The structure that upholds God's truth on Earth is the word(s) of God...God's words; God...
The church(es) are built upon the words of God, not the other way around...
The Catholic religion is built upon the words of men, with a shred of bible thrown in...
Jas_1:21 Wherefore lay apart all filthiness and superfluity of naughtiness, and receive with meekness the engrafted word, which is able to save your souls.
The words of God save us, not the words of men in any church or any where else...
Joh_17:17 Sanctify them through thy truth: thy word is truth.
God's words are truth, not the words of men which are added to the Bible...
Just because your religion makes the claim and you and others agree with it doesn't mean there's an ounce of truth to it...Doesn't matter what you say...It what God says that matters...And we all have that record of the saving words of God...
I never noticed...
I'm more better than you; 'cause I can get 100 into mine!
Like I said; that's how YOU guys parse it.
