Adhering to the Biblical Christian faith, International Lutheran Church teaches and responds to the love of the Triune God: the Father, Creator and Sustainer of all that exists; the Son, Jesus Christ, who entered into our human estate to suffer and die for the sins of all people and rose again to life and victory over death and Satan; and the Holy Spirit, who creates and sustains faith through the Word and Sacraments.
Lutheran Christians often refer to the three solas (Latin for 'alone') as a summary of the faith that gives them hope:
Grace alone - God loves all the people of the world, even though all have turned away from Him in sin. He sent His Son Jesus to love the unlovable and save the ungodly. God's grace is extended to us that we might live in His presence both in this world and the next.
Faith alone - By His suffering and death as the substitute for all people of all time, Jesus purchased and won forgiveness and eternal life for them. Those who hear this Good News and believe it have the eternal life that it offers. By the work of the Holy Spirit, God creates faith in Christ and gives people forgiveness through Him.
Scripture alone - The Christian Scriptures (Old and New Testaments) are the Word of God and are the only reliable source that shows God's will and His plan for our salvation in Jesus Christ. It is the only basis for faith and Christian teaching.
