Church vs Catholic

Though this is a website against faith only, since this theology came from Catholocism we should understand the origin of Catholocism. Many believe they go back to the true church, which is likely true. Yet tracing yourself to the true church does not mean you are the church.

1Jn 2:19  They went out from us, but they were not of us; for if they had been of us, they would no doubt have continued with us: but they went out, that they might be made manifest that they were not all of us. 

There were many people who at one point were connected to the church but were unfaithful in their dealings. During the Council of Nicea a large part of the population believed Christ was created, thus a clear indication that the faithful were intermixed with the unfaithful.

We see the true and false interacting together. All groups could claim to be the true church because they at some point appeared with the true. Jesus did not propose there would always be a clear separation physically. Only spiritually.

1Jn 2:5  But whoso keepeth his word, in him verily is the love of God perfected: hereby know we that we are in him. 

also Jesus pointed out the true and false would be together at times 

Mat 13:30  Let both grow together until the harvest: and in the time of harvest I will say to the reapers, Gather ye together first the tares, and bind them in bundles to burn them: but gather the wheat into my barn. 

There have been from the days of the Apostles the true and false together.

No one by history can 100% prove they are the true. Just do what Christ gave in faith and you are.
