1451 Among the penitent's acts contrition occupies first place. Contrition is "sorrow of the soul and detestation for the sin committed, together with the resolution not to sin again."[Emphasis added.]1452 When it arises from a love by which God is loved above all else, contrition is called "perfect" (contrition of charity). Such contrition remits venial sins; it also obtains forgiveness of mortal sins if it includes the firm resolution to have recourse to sacramental confession as soon as possible.
1456 Confession to a priest is an essential part of the sacrament of Penance: "All mortal sins of which penitents after a diligent self-examination are conscious must be recounted by them in confession, even if they are most secret and have been committed against the last two precepts of the Decalogue; for these sins sometimes wound the soul more grievously and are more dangerous than those which are committed openly."
1458 Without being strictly necessary, confession of everyday faults (venial sins) is nevertheless strongly recommended by the Church. Indeed the regular confession of our venial sins helps us form our conscience, fight against evil tendencies, let ourselves be healed by Christ and progress in the life of the Spirit. By receiving more frequently through this sacrament the gift of the Father's mercy, we are spurred to be merciful as he is merciful.
56 Q. If one has only venial sins to confess, must he be sorry for all of them?
A. If one has only venial sins to confess it is enough to repent of some of them for his confession to be valid; but to obtain pardon of all of them it is necessary to repent of all he remembers having committed.
57 Q. If one has only venial sins to confess and if he does not repent of even one of them, does he make a good confession?
A. If one confesses only venial sins without having sorrow for at least one of them, his confession is in vain; moreover it would be sacrilegious if the absence of sorrow was conscious.
58 Q. What should be done to render the confession of only venial sins more secure?
A. To render the confession of venial sins more secure it is prudent also to confess with true sorrow some grave sin of the past, even though it has been already confessed.
59 Q. Is it well to make an act of contrition often?
A. It is well and most useful to make an act of contrition often, especially before going to sleep or when we know we have or fear we have fallen into mortal sin, in order to recover God’s grace as soon as possible; and this practice will make it easier for us to obtain from God the grace of making a like act at time of our greatest need, that is, when in danger of death.
Catechism of Pope St Pius X.
If baptism is what saves a Roman Catholic, and mortal sin causes one to lose their salvation....why doesn’t the Roman Catholic have to be re-baptized again in order to regain salvation?
DANG!
