Everyone in Church is a Saint?

"May a merciful God preserve me from a Christian Church in which everyone is a saint!  I want to be and remain in the church and little flock of the fainthearted, the feeble and the ailing, who feel and recognize the wretchedness of their sins, who sigh and cry to God incessantly for comfort and help, who believe in the forgiveness of sins.”

Martin Luther, in Luther’s Works (St. Louis, 1957), XXII:55.
