The doctrine and faith of the LCSA is grounded solely on God’s own Word exclusively as written in the Canonical Books of the Old and New Testament as the inerrant divine truth inspired by the Holy Spirit.
The Lutheran Confessions are accepted as the correct and binding exposition of Holy Scripture; these are the three ecumenical creeds of the ancient church: The Apostle’s Creed, the Nicene Creed and the Athanasian Creed; the unaltered Augsburg Confession and it’s Apology; the Smalcald Articles; the Small and Large Catechism of Luther and the Formula of Concord in both Epitome and Solid Declaration.
Accordingly, the Church sees to it that all congregations are thoroughly instructed in Luther’s Small Catechism, that all evangelists know and acknowledge the unaltered Augsburg Confession as the Confession of their Church and that all pastors bind themselves to the teachings of the Lutheran Confessions in their Ordination Vow.
By virtue of being bound by Scripture and Confessions, the LCSA is aware of the unity of faith with the Church of the Apostles and orthodox Christians of all times. The LCSA is therefore in fellowship with the Lutheran Churches in the whole world, in so far as these churches abide by the teachings of the Lutheran Confessions and act accordingly.
is no church fellowship with congregations and churches which stand on a
different foundation or, who on their part, have fellowship with those
that accept teachings contrary to Scripture.
The aim of the Church is determined by the mandate of Christ. Accordingly the Church dedicates herself to teach the pure Gospel of Jesus Christ to administer the Sacraments according to Christ’s institution. This service in the Kingdom of God is directed to all her members and to those who as yet do not acknowledge the Lord Jesus Christ.
The Church also takes care that her members as followers of Christ serve the needy and suffering fellow beings.
