Re: Hebrews 10:25 and 2 Thes. 2:1. Does the Greek word “episynagoge” in these two verses require a physical building?
No. The Greek word “episynagoge” simply means a gathering together in one place. It could be a specific location such as a home or other meeting place, or in the case of 2 Thes. 2:1, the clouds (1 Thes. 4:17).
