14. We believe that God created man out of the dust of the earth, and made and formed him after his own image and likeness, good, righteous, and holy, capable in all things to will agreeably to the will of God. But being in honor, he understood it not, neither knew his excellency, but willfully subjected himself to sin and consequently to death and the curse, giving ear to the words of the devil. For the commandment of life, which he had received, he transgressed; and by sin separated himself from God, who was his true life; having corrupted his whole nature; whereby he made himself liable to corporal and spiritual death….
15…but by his grace and mercy is forgiven them. Not that they should rest securely in sin, but that a sense of corruption should make believers often to sigh, desiring to be delivered from this body of death. Wherefore we reject the error of the Pelagians, who assert that sin proceeds only from imitation.
23…And the same apostle says that we are justified “freely” or “by grace” through redemption in Jesus Christ. And therefore we cling to this foundation, which is firm forever, giving all glory to God, humbling ourselves, and recognizing ourselves as we are; not claiming a thing for ourselves or our merits and leaning and resting on the sole obedience of Christ crucified, which is ours when we believe in him.
