When I think of the "true church" it includes having the same truth as the apostles taught.
14These things write I unto thee, hoping to come unto thee shortly: 15But if I tarry long, that thou mayest know how thou oughtest to behave thyself in the house of God, which is the church of the living God,
the pillar and ground of the truth. 1 Tim 3:14-15
The
CHURCH is the pillar and ground of
THE TRUTH.
That's why the
TRUE CHURCH is hard to find.
