Disclaimer: I am not trying to be negative, just stating how I felt:
1) Most of their literature does nothing more than produce endless talk about baptism and worship with no instruments.
2) Every week during the Lord's supper, the server seemed to talk about how taking the elements strenghened his walk with the Lord. I believe it is a time to remember what Jesus did for us at Calvary.
3) The song "The Greatest Commandment", sung at the end of many services, was hard to follow. I didn't know what part to sing.
It sounds like they just move in a "same routine" tradition of a sort. I assure you, that is not how it should be.
#1 We are suppose to teach the WHOLE word. Not JUST "no instruments and baptism" but also the love, obedience, faithfulness, learn about the OT (because without understanding the OT, it would be hard to understand the NT since there are lots of quotes pulled from the OT) everything. If you have no elders, and you have a mens meeting, mention this. The flock needs ALL the scriptures information, not just parts and pieces over and over. If you have elders, tell them your concerns. Otherwise meet with the men and tell them.
#2 If you maybe pull the gentleman aside and ask him more in depth about why he doesnt more or less mention 1 Corinthains 11 (Lords supper part) or Matthew 26 (Lords supper part). Maybe you can both get an understanding more. How is he going to know if you dont tell him?
Side question. Do you attend the men's meetings (assuming you have no elders and what not)? Otherwise, if you have elders disregard that question. Instead, why not speak with the elders about your observations. No one can correct anything if you or no one brings anything up.
#3 - It sounds like a tradition being bound to me to have to sing a particular song every single time you guys meet, but I am not there, nor should I say anything against it.
However, why would this be a reason for you to not attend?
Scouts honor I probably sing worse than you. I have even less understanding of all them crazy musical notes in the song book. But over time, I can catch on to others and how they sing each song. Sure I mess up, but the point is to worship our Lord with praise of songs.
Songs are also edifying. Have you ever just stopped on the side to just read the song book? They have valuable lessons from scripture, put in song form.
So even if you have no clue whats going on, lift your voice and sing, regardless of talent.
