Every Christian religion has her unusual features. E.g. no women may become priests in the RCC. Mary as a mother of God, however, is very admired, just as many saints. The focus on certain teachings is put in Protestant churches. I only mention baptism, Sabbath sanctification and other things. My church which refers to Jesus Christ like many other churches also; also has some unusual features. These are differences but no separating differences. Is a Roman Catholic Christian less Christian as an a Protestant or a member of my church because he prays to virgin Mary? I do not think so. And only I wanted to clarify this.
All of us are no matter to which church we belong and what we believe in Christ. Christ is the ribbon which connects us.
