I guess you would say that I am a millennial. People in my age range seem to be moving more and more away from religion. Yet, that isn't always the case and a lot of churches are making targeted attempts to bring them "back into the church," though the church may not be their church.
Organizations like that attempt to make it modern and avoid the traditional aspects of the church. I would run from those churches. If it wasn’t for Orthodoxy I don’t think I would’ve ever been interested in Christianity.
They take away everything I want, tradition, and replace it with everything that I dislike.
I want prayer and reverence.
I want connection.
I want spirituality.
What I do not want is a concert.
The only thing I need a worship service to make me feel is reverence for God and a connection to the generations of saints that have come before me. I find that in a liturgical service and a contemporary service feels like a bad concert for a social club I'm not a part of. It's like the "contemporary" services are more to feel good about oneself rather than to actually grow in one's faith.
Getting people in the door is not the goal of a church worship service.
That's the problem with a lot of American churches.
The charismatic megachurch is a phenomenon that is only possible in the First World, where religion and leisure can significantly overlap.
We view the worship service as an evangelistic tool rather than a means for the worship of God and the edification of the saints. You might fill the church with people but what kind of Gospel are you giving them? But the moment you give them the real thing they will leave. Evangelism was the order of the saints outside the church.
In the rest of the world, people are sticking to the form of worship that the Church has kept since within living memory of the Apostles.
