[VI. Confession of Sin]
"Whom when He saw He said: Go, show yourselves to the priests" (Luke xvii. 14).
"Receive ye the Holy Ghost; whose sins ye shall forgive, they are forgiven them, and whose sins ye shall retain, they are retained" (John xx. 23).
THE whole of the life of Our Lord and Saviour Jesus Christ may be summed up in these words of the Acts: "He went about doing good." He healed the sick, gave sight to the blind, hearing to the deaf, and raised the dead to life.
The healing of the body, however, was to Him a secondary object. The healing of the soul was His mission on earth. He frequently called the attention of His followers to this. For example, He cured the man of the palsy to prove that as man He had the power to forgive sins. Another example is when He gives us in the cure of the lepers a figure of sin and its cure.
Leprosy has always been considered a figure of sin. As leprosy covers the body and makes it disgusting and frightful to behold, so sin covers the soul and makes it hideous in the sight of God. The Old Law required lepers to separate themselves from society until their cure was certified to by the priests who were appointed for this purpose. Our Lord has been pleased, in the New Law, to institute a similar method for the cure of the more fatal leprosy of sin. The spiritual leper, the sinner, is to show himself to the priest, make known the diseased state of his soul, and submit to the inspection and treatment of the priest, who is the divinely appointed physician of the soul. But should we not go directly to God, since God alone has power to justify us? It is true, God alone can effect our justification; but He has appointed the priest to judge in His place and pass sentence in His name. To the priests He has said: "Whatsoever you shall bind upon earth shall be bound in heaven, and whatsoever you shall loose upon earth shall be loosed also in heaven" (Matt. xviii. 18); and again: "Whose sins you shall forgive, they are forgiven, and whose sins you shall retain, they are retained" (John xx. 23). These two texts clearly show that auricular confession as practised in the Catholic Church was taught by Christ. For how could the apostles and their successors, the pastors of the Church, know what sins to bind and retain and what sins to loose and forgive unless the sins were confessed to them and they were allowed to judge?
No matter how numerous or how great these are, provided they are confessed with a sincere repentance, they will be forgiven. And they will be forgiven by the power of the priest. Properly speaking, God alone has power to forgive sins. But no one will deny that He has power to confer this power on others. He communicated this power to His apostles and commanded them, in turn, to communicate it to others by means of the Sacrament of Holy Orders.
That Our Saviour communicated this power to His apostles is evident from the words of St. John: "As the Father hath sent Me I also send you. Receive ye the Holy Ghost; whose sins you shall forgive, they are forgiven." But sin was to continue till the end of the world. Hence the necessity of the means of forgiving sin being coextensive with sin. As the people receive from the priests the Word of God and the cleansing from sin in Baptism, so also do they receive from them the cleansing from sin in confession.
It is certain that the apostles conferred the power of forgiving sins upon others, if we find that those whom the apostles ordained this power. But we find this to be the case.
From the time of Christ until the present the writers of every age tell us that confession of sins was practised. St. John, who lived until the beginning of the second century, says in the 1st chapter of his First Epistle: "If we confess our sins, He is faithful and just to forgive us our sins and to cleanse us from all iniquity."
