The Lord be with you
Who are Christian saints? Martin Luther, commenting on Galatians 5:19, gives us the answer.
But now that the light of truth is shining, we see with utter clarity that Christ and the apostles designated as saints, not those who lead a celibate life, who are abstemious, or who perform other works that give the appearance of brilliance or grandeur but those who, being called by the Gospel and baptized, believe that they have been sanctified and cleansed by the blood and death of Christ. Thus whenever Paul writes to Christians, he calls them saints, sons and heirs of God, etc. Therefore saints are all those who believe in Christ, whether men or women, whether slaves or free. And they are saints, on the basis, not of their own works but of the works of God, which they accept by faith, such as the Word, the sacraments, the suffering, death, resurrection, and victory of Christ, the sending of the Holy Spirit, etc. In other words, they are saints, not by active holiness but by passive holiness.
