Often, yes.
Often, no.
Kind of all depends on the circumstances.
Examples of "often, no" (Unless you plan on lecturing the apostles John & Paul when you get to heaven):
* 9 Anyone who runs ahead and does not continue in the teaching of Christ does not have God; whoever continues in the teaching has both the Father and the Son. 10 If anyone comes to you and does not bring this teaching, do not take them into your house or welcome them. 11 Anyone who welcomes them shares in their wicked work. (2 John 9 to 11)
* 3 For my part, even though I am not physically present, I am with you in spirit. As one who is present with you in this way, I have already passed judgment in the name of our Lord Jesus on the one who has been doing this. 4 So when you are assembled and I am with you in spirit, and the power of our Lord Jesus is present, 5 hand this man over to Satan for the destruction of the flesh, so that his spirit may be saved on the day of the Lord. (1 Corinthians five: three to five)
Example of "often, yes":
* 9 I wrote to the church, but Diotrephes, who loves to be first, will not welcome us. 10 So when I come, I will call attention to what he is doing, spreading malicious nonsense about us. Not satisfied with that, he even refuses to welcome other believers. He also stops those who want to do so and puts them out of the church. (3 John 9 to 10)
The key in the above is to discerningly pinpoint who is actually causing the division? Who are the real provocateurs?
Diotrephes spread false rumors, refused to welcome other believers, and put other welcomers out the church.
The guy in the Corinthian church engaging in sexual behavior became the divider once he flaunted his sexual sin before the whole church. (Paul wasn't the divider for wanting to have him ex-communicated)
And in the case of 2 John, it was the heretics who caused the division, even tho they didn't want to be split away from the Christian church.
They insisted they be accepted as is, heresy and all.
Sorry, your carte-blanche attempt to treat all circumstances as the same doesn't wash. Besides, are you so obtuse that you don't even recognize 'tis Mormonism that from the get-go labeled 100% of the Christian church as "apostates," 100% creedally abominable, and as having professions of faith as 100% corrupt? (Note all of the "all" words in the Mormon "scriptures" of the First Vision...Joseph Smith History - 1 - in the Pearl of Great Price)
Bashing and dividing Christians is satan's work.
Does that include bashing Christians as possible "cross-dressers"?
Does that include bashing Christians who you think are engaging in "satan's work" by your labeling of them as "bashers" and "dividers?"
Often, yes.
