Coming from a Protestant background, I have been taught that there are some fundamentals that we must believe in order to be Christian. In other words, although we must separate ourselves (spiritually) from those who deny the fundamentals of the gospel, we must not divide over those things that might be considered non-essentials.
You bring up excellent points.
I’m just thinking out loud regarding your points
AND
Based on your background,
I have 2 questions for you as well ,
hopefully questions get to the answers you’re looking for.
So
Re: that rule you mention …
essential vs non essential beliefs
Q:
Protestantism regardless of stripe, or name they want to use, is ~ 40,000+ sects, divisions, denominations, etc etc today with each making their own rules and regulations governing each of them.
Who qualifies any of
THEM to set any rules on
what IS and is NOT essential for the whole, when there is THAT much disagreement and division among
them and there is
NO apostolic succession among any of them?
Glenn:
This might be understood as the basis for the legitimate brotherhood between members of different confessing denominations. The essentials would be things like the Trinity (Father, Son, and Holy Spirit), the deity of Christ, the dual nature of Christ (fully God and fully man), the Virgin Birth, man’s sin nature and the sufficiency of Christ’s death to redeem us, etc. So there is this idea of a minimum belief in certain essentials. But is seems that with the Catholic Church there is no such idea. All the doctrines must be accepted.
Q:
since
scripture teaches that those who divide or cause division from the Church established by Jesus,
"don’t serve Our Lord Jesus Christ but themselves and their own selfish appetites"[Rom 16:17…] and if they die in that sin, “won’t inherit the kingdom of God” i.e. won’t go to heaven. [Gal 5:21]
Who then is qualified to determine doctrine and dogma,
a. 40,000 + divided sects of Protestantism,
or
b. the only Church Jesus established Himself, the Catholic Church, and gave all His promises to?
Just thinking out loud with respect to the points you provide.
