The Church is not inside a physical building of any sort. Where ever there are two, or three gathered together in his name there Jesus is. That can be on a street corner, in a car, or just about anywhere. Not only that, but when a person becomes born from above they are translated into the Kingdom of God, and brought to the Heavenly city Zion where the Church is gathered together in the spirit. Jesus sometimes taught in a Church setting, but most of the time it was outside or inside someones home.
Heb 12:22 But ye are come unto mount Sion, and unto the city of the living God, the heavenly Jerusalem, and to an innumerable company of angels,
Heb 12:23 To the general assembly and church of the firstborn, which are written in heaven, and to God the Judge of all, and to the spirits of just men made perfect,
Heb 12:24 And to Jesus the mediator of the new covenant, and to the blood of sprinkling, that speaketh better things than that of Abel.
