Living by Grace
At Orange, the message of Jesus is central to everything we do. We are compelled to live out his message in our actions and through our words. We are a community of imperfect people doing our best to worship a perfect God. We invite you to come as you are and join us for worship.

WHAT WE BELIEVE
CORE VALUES
VISION STATEMENT

Our beliefs can be summarized by the following statements:
Salvation is through the grace of God alone in God’s son Jesus Christ and His sacrifice alone.
God’s greatest desire is for you to see a clear picture of God’s character. When you see God, you will find God’s love irresistible.
Scripture is a road map. The Bible is God’s voice, speaking God’s love for all time and personally to you today.
Jesus never changes in a world that always does. Jesus is Creator, Sustainer, Savior, Redeemer, Friend, God’s Son, and fully God Himself.
God loves you, and wants to give you the highest quality of life imaginable not based upon earthly wealth but based upon God’s joy and peace.
The heart of God is a place where you can experience as home. God loves you, and wants to spend time with you everyday personally, one on one, as two close friends.

Our core values are the beliefs that guide us as we…
Jesus – Our church is centered on Jesus. His life, death and resurrection. We believe salvation is through the loving sacrifice of Jesus. We believe Jesus is God’s perfect revelation of God’s love for humanity.
Scripture – We accept the Bible as God’s message to us for salvation, teach, reproof, correction and training in righteousness so that we may be equipped to do the work of God (2 Timothy 2:16-17). The Bible teaches us about the person of Jesus.
Grace – We believe that it is only by God’s grace that we are saved. There is nothing we can do to earn our salvation. (Ephesians 2:8-9)
Forgiveness – Just as we have been forgiven by God, we must also forgive those that hurt us. (Matthew 6)
Service- We believe service is central to our life of faith. We are intentional about blessing others by being outwardly focused. We serve others with no strings attached.
Relationships – We believe relationships are central to the kingdom of God. We strive to be friendly, warm and open to all people.
Authenticity – We are a real church filled with real people. We don’t pretend to be perfect. We believe for relationships to be real, individuals must be authentic.
Spiritual Growth – The Bible refers to people of great faith as having walked with God. We believe spiritual maturity comes only from walking with God.

Our Vision is to lead people to:
Love God. We ask people to worship service on Saturday mornings to fall more in love with God through worship.
Love Others. We believe it is important to develop deep personal relationships with others and small groups are a perfect opportunity for that to happen.
Serve the World. We believe that Authentic Christianity is about living beyond ourselves. Serving others is essential to practicing our spirituality.

Mark Tatum
Senior Pastor
Pastor Mark Tatum is thrilled to be ministering at the Orange SDA church and in the Orange County community. His greatest desire is for people to fall in love with the magnificence of Christ, and enjoy His community on earth, the church.
He grew up in the La Sierra community of Riverside, California, going through the Adventist Christian school system there. He graduated from La Sierra University in 2004 with a Bachelor’s degree Religious Education. From 2005-2008, he taught Bible and Spanish classes at Mesa Grande Academy in Calimesa, CA. He married his wife,Jimena, who hails from Argentina, in the summer of 2006. From 2008 to 2011, Mark and Jimena went to Andrews University in Michigan, where they worked on Masters Degrees in Divinity and Social Work, respectively. Mark graduated with his “MDiv” degree in 2011. In August of that year they returned to California, where Mark served as a Pastor at the El Centro SDA church, as well as taught Bible classes at Calexico Mission School. They welcomed son Josiah into their family in 2013, followed by daughter Jocelyn in 2015. In late 2016, the family came to live in Orange County and serve in the Anaheim SDA church. District Senior Pastoring at the Orange church, along with associate Pastor Nathaniel Sevilla, began in March 2020. The kids now attend Orangewood Academy, and are in Preschool and Kindergarten, respectively. Pastor Mark is also board chair of the school.
Pastor Mark loves reading a variety of genres, discussing fascinating topics, getting out into nature, and making music on his guitar. He loves the Lord supremely, and has no other goal than helping others find the same fascination and beauty in God: through His creation, His will as revealed in the scriptures, and His self-sacrificial love as exemplified in the life of Jesus Christ, His son.
Pastor Mark is interested in getting to know you, too! Feel free to contact Pastor Mark & say hi! Phone/text: (714) 650-1245, e-mail: prmarktatum@gmail.com.
May God bless you as we seek His will together, and walk in the light of His salvation.

Nathaniel Sevilla
Associate Pastor
I feel so privileged to be a pastor and doing this work for God in the Orange Church and Community. I would be lying if I said I always knew I would be a pastor. For as long as I could remember I wanted to a professional basketball player. Growing up I would spend every waking hour either playing or preparing my body for performance. Unfortunately, when I entered senior year of high school, I had multiple serious injuries and felt God was closing this door. Though I received basketball scholarships from a number of universities I felt this was not the path for me. I began to search. The path of ministry began in 2005 after I graduated high school and attended a 10-week colportuering (selling Christian books door-to-door) summer program. Towards the end of the program I believe God called out to me to surrender my life to Him and when I did He called me to be a pastor.
After the program, I attended La Sierra University in Riverside, California and completed a Bachelors of Arts in Religious Studies/Pre-Seminary with a minor in Biblical Languages in 2009. Upon graduation, I was hired by the Southeastern California Conference and was sent to Andrews University Theological Seminary in Berrien Springs, Michigan, where I completed the Masters in Divinity Program with an Emphasis in New Testament Studies and Youth Ministry in 2012. While in Michigan I was an assistant pastor at South Bend Indiana SDA Church (Fall 2010-Summer 2012). Since then I have pastored at Riverside Community Church and Celebration Center for 4 months, Victorville SDA Church (September 2012-July 2016) as the Associate Pastor for Youth, Laguna Niguel SDA Church (July 2016-March 2020) as the Associate Pastor for Young Adults and Young Families, and now here at Orange SDA Church as the Associate Pastor.
If I had to choose one bible verse that encapsulates God’s call in my life it is found in Psalm 40:2, “He drew me up from the desolate pit, out of the miry bog, and set my feet upon a rock, making my steps secure.” Life is very uncertain but God calls us to experience His abundant life here on earth today. I invite you to join us on this journey here at Orange Church where we truly believe God is in the business of transforming lives to make us better reflections of His love, grace, and truth. Come check us out!
When I’m not working, I will always love playing basketball and recently badminton, running, and swimming, eating Thai food and Netflix with my wife, and going to the park with my two handsome mini-me boys; Joash and Jalon.
