EXPLORE OPPORTUNITIES TO JOIN

OUR TEAM

We are grateful for your interest in the work of our organization and invite you to prayerfully consider applying for an open position that would uniquely fit your skills and passions.

Rooting Ourselves in the Gospel

The Colossian Forum team is made up of dedicated Christians who seek to bring the reconciliation of Christ to a divided society. We orient ourselves through prayerful encounters with God, starting each day with a shared time of Scripture reading as well as liturgical and intercessory prayers.

Embracing Conflict as Opportunity

We don’t just teach others to engage conflict, we implement practices of Christian conflict transformation in our daily organizational rhythms. From staff meetings to one-on-one conversations, we embrace our differences and navigate our disagreements by following our North Star: love of God and love of neighbor.

Maintaining a Culture of Excellence

We believe in working to the best of our ability, whether leaning into conflict or laying the groundwork behind the scenes. We “work with all (our) heart, as working for the Lord, not for people,” because we hold that God has invited us into our tasks, as he seeks to reconcile those within his Church to one another and to himself.

Caring Deeply for One Another

Our staff leans into life together. We share one another’s burdens and celebrate individual achievements. We genuinely care for one another and actively enjoy spending our time together. We structure our work time to leave intentional opportunities to connect as humans, not just colleagues to better understand and grow with one another.
