In a church I am considering attending to see how I like it, called First Presbyterian Church, they have a Traditional Service from 9:30am to 10:30am Sundays and a Contemporary Service from 11:00am to 12:30am Sundays. Their website doesn't say what the difference is at all and why the Contemporary one is half an hour longer. Does anyone have any ideas what the differences might be? I'm new to the Presbyterian church and don't know which one I should attend. Maybe try one this week and the other one the next to see what I like better?
