I have family members in the south that just went thru a split in their church over liberal ideas festering there...... those who opposed left and began their own church...only to find their numbers had been infilitrated who outed the very pastor who had made the transition with them. It was an ugly affair all around. They left the church entirely then.
Just as with some catholics I think the Lord is doing some heavy sifting....and true believers won't necessarily be the ones remaining in the church they're accustomed to attending. Sad to see this happening and yet we are told this would come in the institutionalized churches.....the question remains for many where to go as there apppears to be less and less possibilites of finding a church that isn't liberal, or in the thros of.
The reason liberal churches do not see splits, unless something really radical takes place, is because they see so little to stand for in the first place. Or their particular church is like a god; their real source of security and ultimate object of affection.
Division because of Truth is better than unity without it or in error, though you have to determine what the line will be btwn tolerance and compromise.
What you describe is sad and damnable, but “the time is come that judgment must begin at the house of God: and if it first begin at us, what shall the end be of them that obey not the gospel of God? “ (1 Peter 4:17)
And part of the reason for splits is due to our superficiality and carnality. In these latter days of the latter days we needs to get ready to move out of our comfort zone Christianity and live by faith, even if it means meeting in the forest with no published schedule, and getting killed for witnessing about Christ and standing for righteousness, not advertising our church.
