Every teaching of Concordia is based in the Bible. We often summarize our faith using three simple phrases, coined by the 16th century teacher, Martin Luther, "Grace alone, Faith alone, Scripture alone."
Grace alone is way of expressing the belief that if it were not for the grace of God we would be without hope of salvation. The Father sent His one and only Son to be the payment for every injustice, every wrong, every sin. Through His perfect life and death on the cross, Jesus fulfilled the Father's will. In love for us, Jesus was raised to life on the third day. Through His gracious action we receive forgiveness, life and salvation.
Faith alone means we do not depend on our decision or choice, in fact, we confess that we cannot of our own ability choose or decide to welcome Jesus into our lives. It is the Holy Spirit who works this saving faith in us, through Holy Baptism, and through the study of the Bible.
Scripture alone, as already stated, is the only source and norm for our teaching and our belief.
To learn more about these, and other beliefs we hold, we encourage you to go to LCMS Belief and Practice.
