Finding lasting community at Mariners begins with Rooted.
Rooted is a 10-week small group experience designed to connect you to God, the church, and your purpose. Together, in a group of 10-15 people, you’ll explore the Bible, engage in prayer and serve experiences, share stories, and practice rhythms essential to a healthy spiritual life. These spiritual rhythms aren’t new, or something the church recently created, every one of them is found in Acts 2 where the early church began. We will provide you with a facilitator who is trained to come alongside your group to help you get the most out of the experience. Rooted is available 3 times a year, in January, April and August.
Join us for Rooted this winter, beginning the week of January 10!
