Nonsense. Nowhere in the Bible are the Apostles charged with BUILDINGS. Jesus NEVER tells them to build buildings. The PEOPLE are the church. Wherever they meet, Jesus is there. THAT is Scriptural.
You're missing what I'm saying. Yes, the PEOPLE are the church - but just having a random aggregation of people in a Bible study is NOT a "church." The church - which is always and only local in the Scriptures, there is no such thing as any "universal church" - is a specifically organised body of believers. A church is a body of called-out believers, organised under the leadership of a God-called-and-church-recognised pastor, which fulfills the roles of evangelising the lost and edifying the saints, all to the glory of God. What these folks have in their home Bible study is more akin to a parachurch organisation - which are entirely without any scriptural support whatsoever.
