Church, Bistro and Theatre

What is the purpose of going to church? What is some scripture that says the church should be within the home and family and going to church should be to fellowship with other Christians?

I am a junior in high school and need to start looking into colleges and would really like to go to a good school for theatre. I live in Missouri and would like to stay in the midwest, if not in state. I am interested in acting in straight plays and musical theatre, so I would like a school with a musical theatre major. I want to go to a smaller college with a lot of personal attention and small classes. If anyone knows of any good schools or could direct me to websites with ranking lists for these types of schools I would really appreciate it!
