Sure it does since they all believe differently.
The Catholic denomination(sic)
The Catholic Church isn't a denomination.
there are also many branches within the catholic denomination just as with Protestants.
Incorrect. Different Rites not different denominations.
Your post exposes your deficient acumen on the topic which comes as no surprise.
There are believers in the catholic denominations as well as the Protestant....the unity comes entirely thru their relationship in and with Christ Jesus...not the membership of any denomination...not the church affiliation...these are simply “the gathering” places and among.
I am not in the business of validating or not your comments or questions. However, it is a wonderful thing to know Christ and who we are accountable to...splitting hairs is senseless when in reality it all boils down to the person Of Christ.
