It seems to me that the problem here is pietism, and the distaste that some Evangelicals have for liturgy.
If you could loosen your distaste for liturgy all in the congregation could pray together orally. Then worship would not be a one man show except for the singing.
Insisting on extempore prayer only insures that just one person can pray at a time and the congregation just listens.
To me liturgical prayer is just as ‘sincere’ as extempore prayer. You just have to think about the words and mean them.
I was raised in a fundamentalist church that only allowed extempore prayers, and the prayers were just as mechanical and insincere as any other. One just said the same things as the others, just varying the exact words and inserting “just” at least once in nearly every sentence.
You can start with just saying the Lord’s Prayer, Our Father together as a congregation. The church I was raised in would not even do that, thinking the Lord’s Prayer “too Catholic” and “vain repetition”.
They DO pray together orally, all together. That’s what the music is. It’s prayer by the entire congregation, together. Do you understand that?
My husband and I were Evangelical Protestant for 47 years. Our prayers, and the prayers of many of our relatives and friends, were not (and are not) “mechanical and insincere.” You can speak for yourself, but you can’t speak for everyone else.
We should all stop judging each other. OP, the answer to your question is “Yes, the music is important in an Evangelical/Pentecostal/non-denominational worship service.”
We as Catholics should have no problem with this, because it is not a Mass, it’s a worship service.
OP, if you read the history of Protestantism, you will see that music in the worship service is very important. The very first Protestant movement, Lutheranism, got started in Germany, and Germans LOVE to sing! (That’s me!) So Martin Luther wrote hymns for them to sing, and sing they did, with all their hearts! To this day, some of the very best congregational singing and organ playing will be found in Lutheran churches, and many Lutheran churches offer a “season” of concerts in addition to their church services.
The same is true of many other Protestant denominations. Singing and music is extremely important in these communities. I converted to Catholicism 10 years ago, and what I miss about Protestantism is the glorious music. Yes, contemporary music, and traditional hymns, and traditional praise, and Gospel, and occasionally classical, and magnificent choir anthems, and whole orchestras in some churches and rock bands! Beautiful!
You can call it “entertainment” if you like but you’re wrong, because it isn’t “entertainment.” We weren’t in church to be entertained, and the musicians weren’t making music to entertain people. We were there to worship God together, as a family, and to hear His Word, to give thanks for all He has done for us, especially on the Cross of Calvary, and to give witness to others of His greatness and power. It wasn’t “happy clappy” time–never! Far from it–it was worship time and it was serious and solemn–yes, clapping for the Lord is solemn.
I do wish that those of you who haven’t been there and haven’t lived it would be careful about using pejorative phrases.
Everyone, think about this–I came to Catholicism through the Evangelical Protestant churches (and so did my husband). For 47 years, we breathed and walked and talked and lived and loved in the Evangelical Protestant churches, and those churches led us to Jesus, Who led us to His Church, the Catholic Church.
Who here will criticize that?
