Just remember that church eldership and leadership were moving targets in the early years. Brotherhood slowly gave way to higher and lower class of Christians - the clergy and laity.

At first, Christian elders or seniors were bishops or overseers. Later some became "the bishop".

OK, on this subject of catacombs and death, don't forget what became of the betrayal money given to Judas. It was eventually redeemed and used to purchase land for burial grounds.

This shows that material things have their proper place and that the early church did indeed buy property, though on rare occasions and not comparable to the modern church mortgage.

The great issue is what you are doing wherever you are - not where you are. With respect to honoring God. He doesn't dwell in man-made temples and through faith He is in reach of all who call upon his name.
