"In Romans 7, St. Paul says, "The law is spiritual." What does that mean? If the law were physical, then it could be satisfied by works, but since it is spiritual, no one can satisfy it unless everything he does springs from the depths of the heart. But no one can give such a heart except the Spirit of God, who makes the person be like the law, so that he actually conceives a heartfelt longing for the law and henceforward does everything, not through fear or coercion, but from a free heart."

"This is that mystery which is rich in divine grace unto sinners: wherein by a wonderful exchange, our sins are no longer ours but Christ's; and the righteousness of Christ is not Christ's but ours. He has emptied himself of his righteousness that he might clothe us in it, and fill us with it: and he has taken our evils upon himself that he might deliver us from them."

"Grace is given to heal the spiritually sick, not to decorate spiritual heroes"

"There is on earth among all dangers, no more dangerous thing than a richly endowed and adroid reason, especially if she enters into spiritual matters which concern the soul and God. For it is more possible to teach an ass to read than to blind such a reason and lead it right; for reason must be deluded, blinded, and destroyed."

"Reason is the greatest enemy that faith has; it never comes to the aid of spiritual things, but more frequently than not struggles against the divine Word, treating with contempt all that emanates from God."

"Also when it is a case of only upholding some spiritual tenet, such as infant baptism, original sin, and unnecessary separation, then . . . we conclude that . . . the stubborn sectaries must be put to death."

"The heavenly blessing is to be delivered from the law, sin and death; to be justified and quickened to life: to have peace with God; to have a faithful heart, a joyful conscience, a spiritual consolation; to have the knowledge of Jesus Christ; to have the gift of prophecy, and the revelation of the Scriptures; to have the gift of the Holy Ghost, and to rejoice in God."
