I must ask, are you Fr. Bishoy Kamel who serves in St. Marina's Church in Irvine, CA? If not, do you have this username in honor of the Late Reverend Fr. Bishoy Kamel?
If yes to the latter question, I think it may be best that you change your username because someone reading this may think that Fr. BK from St. Marina's in Irvine has this concern and it may cause problems.
(I hope that made sense!)
That aside, of course a house divided against itself cannot stand. If the church priests do not love each other, the congregation cannot love each other nor can they take what the fathers say seriously. I don't think this is common in our churches.
What you can do to better the situation is: (a) Pray about it, (b) Don't contribute with rumors and gossip, (c) Quell any gossip you hear, (d) Do what you can to make the priests' service easier, etc.
Division among priests usually results when one becomes more popular than the other. So love and respect both priests equally.
