Pastor John Cowan
Transitional Senior Pastor
Our journey began when we committed our lives to Jesus during the 'Jesus Revolution' of the 1970s, singing at coffee houses and churches in Northern California. We helped launch Maranatha! Music and The Word For Today ministries in Southern California.
With our eyes on Jesus, our guiding verse is, "Oh let us magnify the Lord, and let us exalt His Name together." (Ps. 34:3). We pray, "Lord, use us in spite of ourselves," and seek to serve others in His name.
In January 2025, John became the Transitional Senior Pastor at Calvary Chapel Sonora, guiding the church through its transition to new leadership. It’s a blessing to be part of this vibrant, Jesus-loving community.
