As the mission of Cornerstone takes shape, it is imperative that we consider our calling on two fronts:
1. to carry the gospel to marginalized individuals and families.
2. to reach the unchurched people in our communities.

The former group is categorized as those who have strayed away from God and church over the years due to disappointments and frustrations in their previous commitments to church. They are called marginalized because they neither have a church home to grow in their faith nor could they ever completely separate themselves from the church. The latter group is composed of the many who have not discovered the power and hope of the life changing Gospel of Jesus Christ. With the view of the two groups, our mission summarized succinctly in Ephesians 2:19, 20

Cornerstone is a maturing Asian-American family church that exists to bring the good news of Jesus to our diverse community in Lansdale and the greater Philadelphia area. Our aim is to know and experience God in three tangible ways: Up-reach in relationship with God; In-reach for personal renewal; Out-reach towards our community.
