The Church is defined visibly by who is and who is not invited to the Holy Communion. Violations occur, but we don’t have “sects”.
That, of course, is not Scriptural.
The church is defined as those who have been given faith in Jesus Christ as Lord, King and Savior.
...And the Lord added to the church daily such as should be saved." -- Acts 2:21;47
"Be not afraid; only believe." -- Mark 5:36"And it shall come to pass, that whosoever shall call on the name of the Lord shall be saved...
What a racket the RCC has going for itself -- mesmerizing people into believing there is salvation in a crumb of flour and water and that that crumb is magically morphed into the body of Jesus Christ only when a priest says the correct incantations and raises it above his head to just the correct elevation.
The RCC teaches there is no salvation without a priest and his mojo. And there is no priest without a magisterium declaring that priest to be "another Christ."
Shameful. Repent of these superstitions that demean Christ's accomplished, one-time, perfect sacrifice on the cross. It is finished.
Whereof the Holy Ghost also is a witness to us: for after that he had said before, This is the covenant that I will make with them after those days, saith the Lord, I will put my laws into their hearts, and in their minds will I write them; And their sins and iniquities will I remember no more. Now where remission of these is, there is no more offering for sin." -- Hebrews 10:14-18"For by one offering he hath perfected for ever them that are sanctified.
