Upon entering the church, at all times, but especially during church services, an individual should remember that he or she is in the House of God. (1 Tim. 3:15). Reverence and good manners are required so as not to disturb those who are already engaged in prayer and worship, but even more importantly, as an expression of sincere fear, faith, and awareness of the presence of the Sovereign God of Celestial Church and the Universe.
You must be properly and appropriately dressed without any loose buttons before coming into the Sanctuary, otherwise, the warden will politely ask that you do it right
All must not wear transparent or tight regalia (Soutana) to the church. It is ungodly. Therefore, appropriate and respectful clothing should be worn at all times. We do this not to impress or spiritually deny each other but to show our Lord that we offer our best to mirror the saints; for He deserves only our reverence, fear, and holiness.
Psalm 96:9; 1 Peter 1: 15-17.
