I always thought it was God who is the pillar and pedestal of truth, not some church.
1 Timothy 3:15 But if I tarry long, that thou mayest know how thou oughtest to behave thyself in the household of God, which is the assembly of the living God, the pillar and ground of the truth. It is the assembly of God that is to uphold and support the truth of God here on earth. That "household" consists of all true and faithful followers and believers in Christ. One of the "truths" contained in scripture is that anyone who aspires to leadership in that household is to conform to the ( ) set by the Holy Spirit through Paul.
1 Timothy 3:2 A bishop then must be blameless, the husband of one wife, vigilant, sober, of good behaviour, given to hospitality, apt to teach; 3 Not given to wine, no striker, not greedy of filthy lucre; but patient, not a brawler, not covetous; 4 One that ruleth well his own house, having his children in subjection with all gravity;
The Catholic Church couldn't even uphold that basic truth. The Catholic Church doesn't qualify.
