About

At Cornerstone, we embrace the core issues of Christianity and present them in a way that is real, smart, brave, and fun. We care about you, and have made a place for you here. We hope you’ll find our non-traditional approach to church refreshing.

Our Mission

Our mission is to reach people, make disciples and build relationships. At Cornerstone Community Church, we place a high emphasis on helping you and your family connect with God and others.

Our Story

Our Leadership

Cornerstone is led by our senior pastor, a strategic leadership team and our pastors and directors. If you’re looking for someone to blame, you’ve found the right spot.

Ron Armstrong

Senior Pastor

Pastor Ron is the founding pastor and primary speaker at Cornerstone. He is a natural storyteller with an extraordinary ability to help people understand the Bible in ways that apply to everyday life. He has a Bachelor of Science in Law, a Masters Degree from Azusa Pacific University, Juris Doctor from Western State (yes, he’s a lawyer), and a Doctor of Education from Brandman University. He is an adjunct professor at Azusa Pacific University and also for Calvary Chapel Bible College. We’ve taken a survey and he is in fact too smart for his own good.

When you hear him speak, expect to laugh and occasionally cry, and when you least expect it, something he’s saying will sneak up on you and you’ll suddenly realize, “that was for me.” Ron and his wife Deb have been married for a really long time and raised two boys. They tragically lost their eldest son, Ryan, but are grateful for the joy both boys have brought into their lives. He is an avid reader and was selected by Barnes & Noble as “the customer most likely to help us stay in business.”

Andy Deane

Associate Senior Pastor

Pastor Andy is the Associate Senior Pastor of Cornerstone. He has a passion for God’s Word and loves to teach people how they can engage with it for themselves, which is why he wrote the book, Learn to Study the Bible. He has a Bachelor of Science in Information Systems Management from New York University, a Masters of Arts in Theological Studies from Veritas Evangelical Seminary, and is just about finished with a Masters of Divinity at the Southern Baptist Theological Seminary. Andy also serves as adjunct faculty at Calvary Chapel Bible College where he teaches classes on Bible Study Methods, Disciple Making, and some books of the Bible.

On September 11th, 2001, God first became real to Andy as he found himself running from the collapsing Twin Towers in NYC. That’s obviously a longer story, and if you’d like to hear it now you can watch this short video. Andy is married to Shannon and has three cute kids: Abigail, Gideon, and Titus. The Deane family lives in Murrieta right near In-N-Out (that’s kind of why they bought that house) and they would love to get to know you more. In fact, if you attend Cornerstone, you can join them for lunch on a Sunday after church by clicking here.

Our Team

Cornerstone believes that we are better together. Our staff has a blast serving Jesus, His people, and each other. Let us know how we can help you grow in your relationships, develop your gifts, and find success in your life.

Our Beliefs

We recognize that there are some CORE issues of Christianity and some PERIPHERAL issues. An example of a CORE issue would be the resurrection of Jesus. The only opinion taught is that there was a physical resurrection of Jesus. An example of a PERIPHERAL issue would be how often you should take communion. It is an issue about which there is room for more than one opinion. Whether to sing hymns or choruses is a PERIPHERAL issue while the fact that we only come to God through Jesus is a CORE issue.

IN CORE ISSUES – WE HAVE UNITY

“There is one body and one spirit…there is one Lord, one faith, one baptism, and one God and Father of us all.” Ephesians 4:4

IN PERIPHERAL ISSUES – WE HAVE LIBERTY

“Accept him whose faith is weak, without passing judgment on disputable matters. Who are you to judge someone else’s servant? To his own master he stands or falls…so then each of us will give an account of himself to God…so whatever you believe about these things keep between yourself and God.” Romans 14:1, 4, 12, 22

IN ALL OUR BELIEFS – WE SHOW LOVE

“If I hold in my mind not only all human knowledge but also the very secrets of God, and if I have the faith that can move mountains but have no love, I amount to nothing at all.” 1 Corinthians 13:2

A HEALTHY CHURCH…

At Cornerstone we are confident enough in the truth of the gospel that we don’t get nervous if someone doesn’t believe even on a core issue. Although we will never allow alternative teaching on core issues, we do believe in giving people time to realize the truth.

ABOUT HUMAN BEINGS…

People are made in the spiritual image of God, to be like him in character. People are the supreme object of God’s creation. Although every person has the tremendous potential for good, all of us are marred by an attitude of disobedience toward God called “sin”. This attitude separates people from God and causes many problems in life. Genesis 1:27; Psalm 8:3-6; Isaiah 53:6; Romans 3:23; Isaiah 59:1,2

ABOUT SALVATION…

Salvation is God’s free gift to us but we must accept it. We can never make up for our sins by self-improvement or good works. Only by trusting in Jesus Christ as God’s offer of forgiveness can anyone be saved from sin’s penalty. When we turn from our self-ruled life and turn to Jesus in faith we are saved. Eternal life begins the moment one receives Jesus Christ into his life by faith. Romans 6:23; Ephesians 2:8,9; John 14:6, 1:12; Titus 3:5; Galatians 3:26; Romans 5:1

ABOUT ETERNITY…

People were created to exist forever. We will either exist eternally separated from God by sin, or eternally with God through forgiveness and salvation. John 3:16; John 14:17; Romans 6:23; Romans 8:17-18; Revelation 20:15; 1 Corinthians 2:7-9
