I have survived two church splits in my life.
In the first, the pastor gradually grew to believe that the miracles in the bible were allegorical rather than historical and are intended to teach us how to live "good lives". His long time relationship with the Elder Board made consensus to remove him impossible, and his views made it impossible to stay in good conscience. It was a "split" by slow attrition over about a year as 3/4 of the elder board stepped down and half the congregation left for other churches. [A boon for several young pastors just trying to build a church in the county]
The second involved a pastor that had an affair, divorced his wife, married his mistress and refused to step down. I was not a member of that church, but the denomination that owned the building sided with the pastor over the members so about 80% of the members left and about half of them rented a building and advertised for a new pastor apart from the old denomination. I attended the new church (post split).
Would you force those people together?
Would you be the one to decide who is damned and expel them?
I do not believe that splits happen lightly.
Are you prepared to submit to the Authority of the Eastern/Oriental Orthodox Church (the only church not to split off)?
The Bible identifies the true faith sir, of course each of us must determine which faith that is, it is quite easy, here are 10 ways to identify it beyond any reasonable doubt. Does your faith meet all these qualifying identifiers?:
One faith Eph 4:5
1. The one faith would worship the God Jehovah exclusively. (Matthew 4:10) Jesus said to him: “Go away, Satan! For it is written: ‘It is Jehovah your God you must worship, and it is to Him alone you must render sacred service.’” (It was written at Deut 6:13).
2. The one faith will not participate in war. Paul stated: (2 Corinthians 10:3) . . .For though we walk in the flesh, we do not wage warfare according to what we are in the flesh. . .
3. The one faith approaches Jehovah through Jesus, Paul said:
(1 Timothy 2:5) . . .For there is one God, and one mediator between God and men, a man, Christ Jesus. . .Jesus said: (John 14:6) . . .Jesus said to him: “I am the way and the truth and the life. No one comes to the Father except through me. . .
4. Jesus said the one faith would be known by the love of its adherents:
(John 13:34, 35) . . .I am giving you a new commandment, that you love one another; just as I have loved you, you also love one another. 35 By this all will know that you are my disciples—if you have love among yourselves. . .
It’s adherents would imitate Jesus,
Peter said: (1 Peter 2:21) . . .to this course you were called, because even Christ suffered for you, leaving a model for you to follow his steps closely. . .
5. The one faith will preach the good news of the Kingdom of God, as mankind’s only hope, not a worldly government, Jesus stated:
(John 18:36) . . .“My Kingdom is no part of this world. . . .
He told us to: (Matthew 6:33) 33 “Keep on, then, seeking first the Kingdom and his righteousness, and all these other things will be added to you.
Jesus stated the main reason he came to earth: (Luke 4:43) . . .“I must also declare the good news of the Kingdom of God to other cities, because for this I was sent.”
He assigned his followers to: (Matthew 28:19) . . .Go, therefore, and make disciples of people of all the nations,. . ., 20 teaching them to observe all the things I have commanded you.
6. The one faith accepts the Bible as the inspired message of God, Paul said:
(2 Timothy 3:16) . . .All Scripture is inspired of God. . .
7. The one faith would appear to be formed in the last days, it’s adherents would be highly educated through instruction, and would live the teachings in their lives: Isaiah wrote: (Isaiah 2:2, 3) . . .In the final part of the days, The mountain of the house of Jehovah Will become firmly established . . .And to it all the nations will stream. 3 And many peoples will go and say: “Come, let us go up to the mountain of Jehovah, To the house of the God of Jacob. He will instruct us about his ways, And we will walk in his paths.
8. The one faith would not set men on high, with religious titles, Jesus said: (Matthew 23:8-10) 8 But you, do not you be called Rabbi, for one is your Teacher, and all of you are brothers. 9 Moreover, do not call anyone your father on earth, for one is your Father, the heavenly One. 10 Neither be called leaders, for your Leader is one, the Christ.
9. The one faith does not allow unrepentant sinners to remain among them,
Paul stated: (1 Corinthians 5:11-13) . . .I am writing you to stop keeping company with anyone called a brother who is sexually immoral or a greedy person or an idolater or a reviler or a drunkard or an extortioner, not even eating with such a man. . .“Remove the wicked person from among yourselves.”
10. The one faith does not practice interfaith with other “Christian” faiths. All teach the same thing, and have the same line of thought: (2 Cor 6:14) For what fellowship do righteousness and lawlessness have?
(Phil 2:2) make my joy full by being of the same mind and having the same love, being completely united, having the one thought in mind.
(1 Corinthians 1:10) Now I urge you, brothers, through the name of our Lord Jesus Christ, that you should all speak in agreement and that there should be no divisions among you, but that you may be completely united in the same mind and in the same line of thought.
Jesus said: (John 17:20) . . .“I make request, not concerning these only, but also concerning those putting faith in me through their word. . .in order that they may be one just as we are one.
I hope this helps you sir, and I understand why you left, but keep this in mind, like you mentioned with the first split, you judge a faith by it's teachings, not by the sins of others like the second example.
