Here I am, Lord?

This morning, my friend and I took a trip to Austin High School to attend an Austin Stone service. For those of you who have never heard of it, here are some statements from their about page:
"We love Jesus, God’s Word, and each other. We're taking Jesus' revolutionary message of grace, truth, and compassion to Austin and to the world."
"The Austin Stone is a Church for the City. We're much more than a church to attend, but a community centered on the person and mission of Jesus Christ. We're actively working to build a great Austin, renewed and redeemed by the gospel. "
Does it sound like a cult to you? Because that's kind of what it felt like. I mean I didn't feel like I was being brainwashed or anything I just felt highly uncomfortable. 
I'm so used to the traditional Roman Catholic setting where they sing classic songs and there is a lot of silence and reflection and we we read from the Bible and pray together. This service started like a Christian rock concert, then there was a lecture on the theme for the next few weeks, then more singing.
I feel like Austin Stone is a personal finance class and Catholicism is Calculus. If you have a really engaging professor you can learn a lot in calc, but if he's boring and you can barely stay awake, let alone understand him, then it becomes impossible to learn. Calculus has a lot of practical applications but again if you slept through your professor's explanation you just don't know them. Personal finance on the other hand is different. Of course a bad professor could make it more difficult but you still remember almost everything you learn because it's stuff that you need. All the practical applications work for you almost 100% of the time. You will always need to know how to manage credit cards and insurance and a mortgage, whereas in calc, you only need to know optimization if you're a box manufacturer and you want to use the least amount of cardboard to make a million 2x3x2 boxes.
Listening to the pastor of Austin Stone discuss Bible verses as they apply to us today was new for me. I'm sure my priests do that too but it can be so hard to pay attention and sometimes it feels like I'm too far removed. The pastor at Austin Stone was very engaging and everything he said made so much sense. He taught a valuable lesson but I'm unsure if I want to attend again. It was vastly different from any service I've ever been to. I appreciated the message but I felt light years away from my comfort zone and when it comes down to it, you have to be comfortable with your faith in order to practice it.
I'm sure Austin Stone is a wonderful spiritual outlet for a lot of people but to be completely honest, it scares me and I get a cult-y vibe. I want to spend my hour a week with Christ in a church, singing "Lord of the Dance" and praying the Nicene Creed.

Sincerely,
Mare
