There is only one God, the Father, Son, and Holy Spirit, who created and preserves all things.
Humanity was originally created perfect and without sin, but since the fall of Adam, all people are born sinful and separated from God. They have no ability to free themselves from this sinful condition.
However, Christ, the Son of God, came down to earth and was born of the Virgin Mary as a real human being. In order to pay for the sins of the whole world, Jesus died on the cross and rose again on the third day. Therefore, because of Christ and His work alone, all people have been forgiven or justified before God.
God delivers this forgiveness through certain ways or means, the Word and the Sacraments. These Sacraments are Baptism and the Lord’s Supper. They are God’s work and God’s action which He uses to deliver the forgiveness won by Christ. Through them, God creates and sustains faith within the individual.
Wherever the Word is purely preached and the Sacraments are rightly used, God establishes the Holy Christian Church. All who are saved belong to this Church, even if it sometimes cannot be seen. Because human errors, or false doctrines, lead away from God and into sin, all who recognize their errors should flee from them.
God has also established the Office of the Holy Ministry for public preaching and distributing the Sacraments in His Church. Men are called to this Office through the Church according to the will of God.
Christ will return on the Last Day to judge all people. On that day, all people will be raised in their physical bodies and will go either into eternal punishment in hell or into eternal life. This judgment will come without warning and will be visible to all people. Because of Christ and His work, however, Christians have no reason to fear it.
The Holy Spirit spoke to the prophets and the apostles and made them write the books of the Holy Bible. Therefore, the Bible is the Word of God, His complete and only revelation to humanity. Because of this, the Bible is also without error.
Finally, because Christians are called to confess the truth also in the world, the Lutheran Church adheres to a group of writings called the Book of Concord. These writings are not Scripture, and they do not replace Scripture. The Book of Concord is a public confession of the truth of Scripture, and it is accurate because it reflects the teachings of the Bible.
