I don’t like the word denominations nor do I really like the term “Plymouth-Brethren” for my (so-called) denomination. According to Scriptures the only thing I see Christians being called is Christians or brethren.
When I look out at that vast landscape of Christendom and a person calls themselves a Christian and exhibits the fruit of their profession, I call them brother or sister—so do most of the folk I assemble with. A Christian should be able to embrace all believers as being part of the Body of Christ although acknowledging that others may not be convicted of the same things.
