The church is the pillar of truth- what church?
Timothy 3
15But if I tarry long, that thou mayest know how thou oughtest to behave thyself in the house of God, which is the church of the living God, the pillar and ground of the truth.
If we look at the literal we see the word assembly:
1 Timothy 3
5and if I delay, that thou mayest know how it behoveth [thee] to conduct thyself in the house of God, which is an assembly of the living God – a pillar and foundation of the truth,

Look at in context, just previously we see requirements for a bishop of that Church:
1 Timothy 3
2A bishop then must be blameless, the husband of one wife, vigilant, sober, of good behaviour, given to hospitality, apt to teach;
3Not given to wine, no striker, not greedy of filthy lucre; but patient, not a brawler, not covetous;
4One that ruleth well his own house, having his children in subjection with all gravity;
5(For if a man know not how to rule his own house, how shall he take care of the church of God?)
Paul addresses the men and women of the Church:
1 Timothy 2
8I want men everywhere to lift up holy hands in prayer, without anger or disputing.
9I also want women to dress modestly, with decency and propriety, not with braided hair or gold or pearls or expensive clothes, 10but with good deeds, appropriate for women who profess to worship God.
In
1 Timothy 3 Paul also addresses ovverseers, Deacons and their wives,
Paul even mentions those that will depart from the faith:
1 Timothy 4
1Now the Spirit speaketh expressly, that in the latter times some shall depart from the faith, giving heed to seducing spirits, and doctrines of devils;
2Speaking lies in hypocrisy; having their conscience seared with a hot iron;
3Forbidding to marry, and commanding to abstain from meats, which God hath created to be received with thanksgiving of them which believe and know the truth.
Paul is writting to Timothy and the Church of Ephesus, the entire Church body at Ephesus.
Paul is saying that every Christian as Christ’s representatives to the world must be the pillar and foundation of the truth.
