Any christian wasting time fighting other christians, is being helpful to the enemy of the Lord Christ, and helpful to the enemy of the church established by the Lord Christ on earth, that is, christians attacking other christians are helpful to satan.
That said, the church of christ has been attacked since the very start, but evil will not win over it, because evil can't win against God, and God is the protection and foundation by faith and grace of the real church of christ.
So be strong in faith in the only true God, who sent his Son Jesus Christ on earth to guide and free humanity from evil, by the power of the Holy Spirit of God.
Do God's will, live the gift of life God has granted to humanity out of his goodness, ignore the attacks of evil on the church of the Lord Jesus, since those attacks from the enemy are and will always be worthless and will always fail to ever defeat either of God or his church.
God blesses always everyone, may more people listen God and be sanctified by his Word.
