Psalms 76:10

The first is the thought, the latter are the remnants of the thought. What is the first thought? That from whence we begin, that good thought whence thou wilt begin to confess. Confession uniteth us to Christ. But now the confession itself, that is, the first thought, doth produce in us the remnants of the thought: and those very "remnants of thought shall celebrate solemnities to Thee." What is the thought which shall confess? That which condemneth the former life, that where-unto that which it was is displeasing, in order that it may be that which it was not, is itself the first thought. But because thus thou oughtest to withdraw from sins, with the first thought after having confessed to God, that it may not escape thy memory that thou hast been a sinner; in that thou hast been a sinner, thou dost celebrate solemnities to God. Furthermore it is to be understood as followeth. The first thought hath confession, and departure from the old life. But if thou shalt have forgotten from what sins thou hast been delivered, thou dost not render thanks to the Deliverer, and dost not celebrate solemnities to thy God. Behold the first confessing thought of Saul the Apostle, now Paul, who at first was Saul, when he heard a voice from Heaven!...He put forth the first thought of obedience: when he heard, "I am Jesus of Nazareth, whom thou persecutest," "O Lord," he saith, "what dost Thou bid me to do?" This is a thought confessing: now he is calling upon the Lord, whom he persecuted. In what manner the remnants of the thought shall celebrate solemnities, in the case of Paul ye have heard, when the Apostle himself was being read: "Be thou mindful that Christ Jesus hath risen from the dead, of the seed of David, after my Gospel." What is, be thou mindful? Though effaced from thy memory be the thought, whereby at first thou hast confessed: be the remnant of the thought in the memory....Even once was Christ sacrificed for us, when we believed; then was thought; but now there are the remnants of thought, when we remember Who hath come to us, and what He hath forgiven us; by means of those very remnants of thought, that is, by means of the memory herself, He is daily so sacrificed for us, as if He were daily renewing us, that hath renewed us by His first grace. For now the Lord hath renewed us in Baptism, and we have become new men, in hope indeed rejoicing, in order that in tribulation we may be patient nevertheless, there ought not to escape from our memory that which hath been bestowed upon us. And if now thy thought is not what it was,-for the first thought was to depart from sin: but now thou dost not depart, but at that time didst depart,-be there remnants of thought, test He who hath made whole escape from memory....
