As servants of YHVH, our loyalty must be to Him. We are not to be bound to churches, groups, ideologies, or other people the same way we are to Him. This is one of the lies religious groups promote. It is something I have had to overcome; the idea that I was being disloyal or even disobedient to YHVH by leaving a particular group or fellowship.
When I attended school, 13 years of learning were housed under one roof. You came in at five years old as a kindergartener and graduated from the building as a senior 13 years later. It would have been ridiculous to keep a student in the kindergarten classroom for all 13 years. Each classroom was designed to advance the process of learning and they were all necessary groundwork for the end result. After high school, other institutions were available for more advancement and growth in specific fields.
This is not unlike “church” groups, except that the classrooms are separate churches and the building is the “church” at large. Is this beginning to make sense? At the beginning of my fellowship in the body of Messiah, I was led to believe - never stated explicitly, but always inferred - that my loyalty was first to denominational theology and second to the local body of which I was a member. Imagine the spiritual dissonance when I heard clearly from the Holy Spirit that I needed to leave a certain fellowship. Imagine the flack from leadership and fellow believers that were sure I was wacked.
