Best settings for baptism (indoors) in low light

MrsGrizz1016

This weekend I would like to use my D3100 at church to photograph a relative's Baptism and a bible presentation to my son. I'll be about 20-25 feet away from the action with low light. I am beginner and not really sure which one of my lenses would be best. I have the Nikkor 50mm f/1.8 G, the kit 18-55mm, and the kit 55-200mm. Any suggestions on which lens and settings would be best are much appreciated. Thanks in advance!

Howdy @MrsGrizz1016 - Sorry I didn't get to you sooner. How did the shoot go? If you'd still like some pointers let me know. Also, feel free to post the photos online somewhere (flickr, facebook, google+) and I'd be happy to let you know my thoughts on the settings that you used. All the best!
