It does not make a difference to those who are steeped in dead orthodoxy (such as the Catholics and many Lutherans), but for those alive in Christ it makes all the difference. I am not a good person, Eric, that is why I need the Righteousness of Christ attributed to me, Christ made atonement for my sins, which is the heart of the Gospel, the central message of the Bible, and the reason Christ instructed the Church to partake in communion - as a remembrance of him, nothing more.
