Church is “individuals” who have REPENTED OF THEIR SINS to OBEY JESUS CHRIST AND are under the authority of a man or woman Pastor who is:
(1) Born-again (admitted and turned from sin — to obedience to Jesus Christ),
(2) Jesus-chosen (not man-made),
(3) Anointing-Sent (had a Divine encounter).
The “Anointing” that sends is Jesus Christ, Himself, as the Holy Spirit.
See Revelation 3:9 where ‘Jews’, in this spiritual context, refers to Christians and ‘synagogue’ refers to churches.
NOTHING ELSE IS A CHURCH! Other gatherings are just fellowship, gathering together with the spirit of its leader.
