The Marks of the Church
The Church consists of all those individuals whom God has saved throughout the world. The marks of the Church in her individual congregations are those defining characteristics of the body of Christ throughout history. These marks are, especially, the right preaching of God’s Word and the faithful declaration of the Gospel, the administration of the sacraments of Baptism and the Lord’s Supper, the discipline of her members, and her submission to Christ as her only true and rightful head (1 Timothy 3:13; Matthew 16:19; 28:19; 1 Corinthians 11:24-26).
The Solas of the Protestant Reformation
Sola Scriptura (By Scripture Alone) The Bible is the sole written divine revelation, our only infallible rule for faith and life, and alone can bind the conscience of believers absolutely (Matthew 4:4; 2 Timothy 3:16).
Sola Fide (By Faith Alone) Justification is by faith alone. By God’s free grace, the righteousness of Jesus Christ is imputed to us by faith and is the sole ground of our acceptance by God, by which our sins are pardoned (Romans 5:1; Galatians 2:16).
Solus Christus (Christ Alone)
Jesus Christ is the only mediator through Whose work we are redeemed (John 3:16; John 14:6).
Sola Gratia (By Grace Alone)
Our salvation rests solely on the work of God’s grace for us (Romans 2:4; Ephesians 2:8-10).
Soli Deo Gloria (Glory to God Alone) Salvation is of God and has been accomplished by God, therefore to God alone belongs the glory (Isaiah 42:8; Colossians 3:17).
