Wrong.
It doesn't matter WHICH version of English - whether it is modern English or classic Elizabethan English - the verse comes out the same:
GOD is the "WHO" and the Church is the "WHICH" - and the "WHICH" is the pillar and foundation of truth.
Tell you what - I’ll defer to PROTESTANT scholarship on the matter.
These are not the ravings of an uninformed, angry anti-Catholic like yourself. They are serious scholarship based on serious linguistic research at the doctorate level . . .
Ellicott's Commentary for English Readers
The pillar and ground of the truth.—The imagery is here changed, and the “house of God” which the Apostle had just defined to be the Church, or congregation, belonging to the living God, and in the midst of which He was pleased to dwell, is now defined to be “the pillar and ground” (or, basis) “of the truth.”
Barnes’s Notes on the Bble
The pillar and ground of the truth - There has been no little diversity of opinion among critics whether this phrase is to be taken in connection with the preceding, meaning that "the church" is the pillar and ground of the truth; or whether it is to be taken in connection with what follows, meaning that the principal support of the truth was the doctrine there referred to - that God was manifest in the flesh. Bloomfield remarks on this: "It is surprising that any who have any knowledge or experience in Greek literature could tolerate so harsh a construction as that which arises from the latter method."
Cambridge Bible for Schools and Colleges
The Church is, first, the house of God, and the Son of the living God its centre; and then this house is itself a centre, the central pillar of a larger house, the world, God’s home.
Jamieson-Fausset-Brown Bible Commentary
The Church is "the pillar of the truth," as the continued existence (historically) of the truth rests on it; for it supports and preserves the word of truth. He who is of the truth belongs by the very fact to the Church.
Matthew Poole's Commentary
The universal church (of which the church of Ephesus, over which Timothy had a charge, was a genuine part) is, in the sense before expressed, the pillar and supporter, or seat, of truth.
Vincent’s Word Studies
The idea is that the church is the pillar, and, as such, the prop or support of the truth.
