The canonical Scriptures of the Old and New Testaments as the inspired Word of God and the authoritative source and norm of its proclamation, faith and life, "according to which all doctrines should and must be judged." (Formula of Concord, Epitome, Part I)
The Apostles’, Nicene, and Athanasian Creeds as true declarations of the faith of the Church.
The Unaltered Augsburg Confession as a true witness to the Gospel, acknowledging as one with it in faith and doctrine all churches that likewise accept the teachings of the Unaltered Augsburg Confession.
The other confessional writings in the Book of Concord, namely, the Apology of the Augsburg Confession, the Smalcald Articles and the Treatise, the Small Catechism, the Large Catechism, and the Formula of Concord, as further valid interpretations of the faith of the Church.
The Gospel, recorded in the Holy Scriptures and confessed in the ecumenical creeds and Lutheran confessional writings, as the power of God to create and sustain the Church for God’s mission in the world.
St. John's honors and accepts The Common Confession (included below, as a summary of teachings otherwise affirmed in the Lutheran Confessions.
We are people who believe and confess our faith in the Triune God -- Father, Son, and Holy Spirit. We trust and believe in Jesus Christ as our Savior and Lord.
We believe and confess that all human beings are sinners, and that sinners are redeemed by the death and resurrection of Jesus Christ. God alone justifies human beings by faith in Christ — a faith that God creates through the message of the Gospel. As ambassadors for Christ, God uses us to speak his Word and build his kingdom.
We believe and confess that the Bible is God's revealed Word to us, spoken in Law and Gospel. The Bible is the final authority for us in all matters of our faith and life.
We accept and uphold that the Lutheran Confessions reliably guide us as faithful interpretations of Scripture, and that we share a unity and fellowship in faith with others among whom the Gospel of Jesus Christ is preached and the sacraments are administered in accordance with the Gospel.
We believe and confess that the Holy Spirit makes all who believe in Jesus Christ to be priests for service to others in Jesus' name, and that God desires to make use of the spiritual gifts he has given through the priesthood of all believers.
We believe and confess that the marriage of male and female is an institution created and blessed by God. From marriage, God forms families to serve as the building blocks of all human civilization and community. We teach and practice that sexual activity belongs exclusively within the biblical boundaries of a faithful marriage between one man and one woman.
We believe and confess that the church is the assembly of believers called and gathered by God around Word and Sacrament, and that the mission and ministry of the church is carried out within the context of individual congregations, which are able to work together locally and globally.
