The International Church of Luzern proclaims the following historic, Protestant essentials of biblical faith:
- The Holy Bible, containing the 66 books of both the Old and New Testaments, is inspired by God and contains everything a person needs to know and to do for a right relationship with God and people.
- There is only one God, the infinite Creator, Sustainer, Ruler, Judge, Lover, and Redeemer of all things, who is eternally existent in three persons: God the Father, God the Son, and God the Holy Spirit.
- Humans are created in God’s image for a personal relationship with God, but have disobeyed God and become alienated from Him as a consequence of that disobedience.
- Jesus is the Messiah, promised in the Old Testament, the Word of God and the Lamb of God. He became human in order to reveal the Father to us and to pay the death penalty on our behalf for our disobedience. He died on the cross and conquered death on our behalf by physically raising from the dead on the third day.
- The Holy Spirit is the manifestation of God’s presence on earth in order to continue the ministry of Jesus. The Holy Spirit empowers people to repent from sin, to trust in the work of Christ at the cross and over the grave, and to follow Jesus as His disciples.
- Salvation means to be spared God’s judgment against our disobedience. It is an unearned gift from God through faith in Christ. None of our good works can earn us eternal life.
- There is a literal Heaven and a literal Hell. Every person has an immortal soul which will spend eternity in either Heaven or Hell. Faith in the work of Christ is the sole criterion for where a person spends eternity.
- Jesus will physically return to earth to bring Judgment Day on which His followers receive eternal life in the presence of the Father and those who rejected Him receive eternal separation from God.
- The Church is that body of people, past, present, and future, who have repented from sin and trusted in the work of Christ for forgiveness from sin to become daily followers of Jesus. The Church exists to fulfill the Great Commission to make disciples for Jesus among all nations and to strengthen those disciples.
