Am I wrong to let small group meetings bother me?

Answer:

You are asking the wrong question. Whether something bothers me or not doesn't indicate whether it is right or wrong. If I demand a change be made because it bothers me, then I am making myself the standard that everyone else must conform to. Thus, the real question is whether the situation is authorized by the Lord.

Congregations must meet on the first day of the week to worship the Lord. This meeting is a gathering of the entire congregation -- "If the whole church assembles together" (I Corinthians 14:23). I take it that this is what is happening on Sunday mornings. On Sunday evenings, the whole church is not gathering together, so it cannot be considered an assembly of the church. It would be similar to a church dividing up for Bible studies, it is just that some are meeting at a different location.

Personally, I don't see how such divisions help promote a unified whole. Better would be to follow the apostles' teachings: "And He gave some as apostles, and some as prophets, and some as evangelists, and some as pastors and teachers, for the equipping of the saints for the work of service, to the building up of the body of Christ; until we all attain to the unity of the faith, and of the knowledge of the Son of God, to a mature man, to the measure of the stature which belongs to the fullness of Christ. As a result, we are no longer to be children, tossed here and there by waves and carried about by every wind of doctrine, by the trickery of men, by craftiness in deceitful scheming; but speaking the truth in love, we are to grow up in all aspects into Him who is the head, even Christ, from whom the whole body, being fitted and held together by what every joint supplies, according to the proper working of each individual part, causes the growth of the body for the building up of itself in love" (Ephesians 4:11-16). It is the united effort that should be emphasized.
