Small Groups

There is a long history of building into lives as fellow believers that has energized the ministry and mission of COD. We offer a number of ways for adults to connect, grow and be involved: weekly small groups (HUB groups) in homes, discipleship opportunities, and various Bible classes on Sunday mornings.

HUB Groups

These are mini-communities that meet in the homes across the San Gabriel Valley throughout the week. The love and grace of God are meant to be experienced in community, and at COD we seek to live that out with each other. This leads to deep, redemptive, authentic relationships that help us not only learn of God’s love and care, but to see it in real life. For most of us this begins in our small group environment, HUB groups. From our experience, it’s the best way to settle into our faith family.

What is Discipleship? Discipleship just means personal training in the Way of Jesus. It means spending time with a more mature believer who is willing to share life experience with you, and show you how to walk with Christ Jesus. Disciplers at Church of the Open Door use a series of Bible guides to help you over the thresholds of spiritual maturity. A discipler is like a personal coach or spiritual trainer whose goal is to help you grow in Christ and equip you to pass this life on to others.

Sunday Morning Small Groups

Essentials of the Faith

This class meets at 9:30am for 50 minutes on Sunday morning. The format of the class is “discussion”, and everyone is encouraged to participate. Class facilitator Brian Booth guides the discussion using a Navigator’s workbook. About 20 people attend and the class meets from September through June. Visitors welcome!

Friendship Class (Hillside)

Join this 9:15am class designed with senior adults in mind. It’s taught by Dan Waldron and facilitated by Jim Davis. This class starts with two or three hymns from one of the two downtown hymnals. Then they enjoy a Bible lesson, a report on missionary needs and activities, and end with a time of prayer.

Women’s Bible Class (U62)

Join Judy Cocoris at 9:30am as she teaches this class for women. They focus on studying books of the Bible, although they get into topical studies along the way. There is always lively discussion, and (for energy for all of this!) they start off with donuts and coffee. Women of all ages are welcomed!

Women of Grace (U30)

While this class is especially for women who come to church alone for whatever reason, it is our desire that any lady at COD would feel welcome to join us to invest time and effort in a group that studies the Word and experiences deep fellowship with one another. Led by a team of ladies at 9:30am.

Spanish Ministry (H20)

Join with others who enjoy having fellowship in Spanish! This class meets at 9:30am on Sunday mornings, and enjoys connecting with each other around food and Bible study.


This group meets at 9:30am to provide support and care for each other as they navigate relationships with adult children and other realities unique to midlife.
