OUR LEADERSHIP TEAM

The Leadership Team (LT) at Cornerstone is a group of congregation-approved members who oversee the church both spiritually and operationally. It is a group made up of between 5 and 9 people that operate on year-long terms starting in August. In many other churches, the analogous leadership is structured as Elders and Deacons.


On the operational side, the LT oversees church finances, makes sure we have a place to worship, and takes care of other business matters. On the spiritual side, the LT makes sure the Pastoral Staff has accountability and are taken care of and keep a general pulse of the congregation’s health. The overall goal is to maintain Cornerstone’s health as a Christ-centered community. Who is currently on the Leadership Team? The LT currently consists of 5 members plus our Lead Pastor, Bill Johnson.

Frequently Asked Questions

About The Leadership Team


How do members become part of the Leadership Team?

The existing Leadership Team creates a nominating committee that facilitates nominations from the congregation for new LT members. Criteria include being a member as well as the Biblical qualities as noted in 1 Timothy 3. After a series of interviews, prayer, and discernment, LT-approved candidates are brought before the congregation for a vote of approval. 

What are some concrete examples of the Leadership Team's oversight?

  • Spiritually discerns church vision and strategy
  • Sets, approves church budget
  • Sets major events in church calendar
  • Works to resolve any conflicts within the church
  • Provides accountability, help, resources for Staff
  • Oversees the formal members of Cornerstone

How can I get more insight into what the Leadership Team is doing?

The LT will post a monthly report of things the LT has been discussing and working on Cornerstone Connect (sans any sensitive information relating to certain individuals). You can also always ask questions to individual LT or staff members, or send an email to everyone here.

If I have any concerns or questions, should I bring them up to the Leadership Team?

Absolutely! Anyone on LT should be one of the primary points of contact for any issues or questions that may come up for anyone in the congregation. The Pastoral Staff Team is also a resource, of course, but sometimes it is more comfortable for a congregant to approach a lay-leader.
