37. Any true Christian, whether living or dead, participates in all the blessings of Christ and the church; and this is granted him by God, even without indulgence letters. What is the best summary of this statement

The criterion expressed here comes from the Protestant, Lutheran belief. The Lutheran belief states that any Christian can get God's grace and thus, salvation, through faith only. Buying divine favor such as paying indulgences for the forgiveness of sins is not right nor it leads to salvation.
