“I am writing to you…so that you will know how people ought to conduct themselves in God’s household, which is the church of the living God, the pillar and foundation of the truth.”

And the early church met in people’s houses where the Word would be read.

So maybe that pillar and foundation of the truth is the Holy Spirit indwelling believers irrespective of ANY external circumstance whether a prison cell, a home or an overly done building.

Yes, we have all been given the Holy Spirit as our Helper.
