Our Mission & Vision

The mission of Cornerstone is to love God, to love others, and to magnify the name of Jesus Christ. Our vision is to

  • Share the good news of Jesus Christ to all of those who have not heard, first in Lancaster and then in all the world (wherever we go).
  • Provide a place of Biblical worship and instruction in the Word of God.
  • Provide assistance to the best of our abilities and resources to those in need.

We desire to set people free who have been held captive by drugs and alcohol and sickness;  to love the unlovely, to edify believers and to raise up a united fellowship of believers.  Our passion and goal is to equip the believers for the work of the ministry.

Our History:

Cornerstone was originally founded on Easter Day 1988 in the basement of Pastor Tom & Tammy’s home.  The name of the church family was New Testament Ministries.  Cornerstone has served the city of Lancaster by preaching the solid Word of God in two weekly services.   We are involved in weekly jail ministry.  We have a thriving and growing group of people who have a love for God and what He is doing in the earth by His mighty Spirit.

Pastor Tom was born and raised in Carroll, OH.  He was born-again in January 1973 at 10 years old.  Pastor Tom felt called to be a pastor when he was a freshman in high school.  His work in the ministry began by teaching Children’s Church and leading praise and worship at a non-denominational church in Lancaster, OH.  The road of ministry included youth pastor and then pastor.  He is the founder of New Testament Ministries which later became Cornerstone New Testament Church.

Tammy is from Lancaster, OH and was raised in church from a very young age.  She began singing in the youth choir at age 10.  She has served God in praise and worship through singing and playing the piano.  Pastor Tom and Tammy met as teenagers at a  youth meeting and began leading praise and worship together after they were married.  They have been married since 1983 and have two sons, a daughter and son-in-law and a grandson.
