We are aware of our sinful human nature, and that we are saved by "grace alone."
"Amazing Grace" is a beautiful but doctrinally flawed song, and is not inspired Scripture.
The term "wretch" suggests Calvin's doctrine of "total depravity," which is contrary to Church Teaching.
We believe:
CCC 405. Although it is proper to each individual, original sin does not have the character of a personal fault in any of Adam’s descendants. It is a deprivation of original holiness and justice, but human nature has not been totally corrupted: it is wounded in the natural powers proper to it, subject to ignorance, suffering, and the dominion of death, and inclined to sin — an inclination to evil that is called “concupiscence.” Baptism, by imparting the life of Christ’s grace, erases original sin and turns a man back towards God, but the consequences for nature, weakened and inclined to evil, persist in man and summon him to spiritual battle.
The scriptures disagree with your religion...
Rom 3:23 For all have sinned, and come short of the glory of God;
Rom_5:12 Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned:
The fact that people sin automatically disqualifies them from a spot in heaven...ONe sin...That's all it takes...A person in that state is surely wretched...
If that was not true, we would have no need for a Savior...
