We teach and respond to the love of the Triune God: The Father, creator of all that exists; Jesus Christ the Son, who became human to suffer and die for the sins of all human beings and to rise to life again in the ultimate victory over death and Satan; and the Holy Spirit, who creates faith through God's Word and sacraments. The three persons of the Trinity are coequal and coeternal - one God.

SLS accepts and teaches the Bible-based teachings of Martin Luther. These teachings inspired the Reformation of the Christian church in the 16th century. The teachings of Luther and the reformers can be summarized in three phrases:

Grace Alone
Faith Alone
Scripture Alone

God's word is at the center of all that we do. Each teacher integrates faith into all subject areas. We use the Concordia Publishing House series "Enduring Faith" for our religious instruction.

Weekly chapel services are part of our educational program. Chapels are led by area Lutheran pastors, classrooms, and other Christian guests. Our students serve in chapel, both in leadership and support roles. SLS supports Christian organizations with our chapel offerings.
