Every Catholic man has inherited a desire to commit sins which can separate him from God. A man’s sins vary in type and severity; all sins damage a man’s union with God but mortal sin causes a man to fall from God’s grace on earth and to lose Heaven and gain Hell if he dies guilty of mortal sin. 

Men are in an unavoidable battle against sin

Sin is a deliberate thought, word, deed or omission contrary to the eternal law of God, which is an offense against God and neighbor (CCC 1849-1851).  Because of Original Sin (CCC 418), all men are inclined to sin (concupiscence), leaving men in a life-long battle with sin (CCC 409).

Men commit various types of sins

“Sins can be distinguished according to their objects, as can every human act; or according to the virtues they oppose, by excess or defect; or according to the commandments they violate. They can also be classed according to whether they concern God, neighbor, or oneself; they can be divided into spiritual and carnal sins, or again as sins in thought, word, deed, or omission” (CCC 1853).  

Venial sin injures. Mortal sin kills.

“Venial sin allows charity to subsist, even though it offends and wounds it” (CCC 1855); “deliberate and unrepented venial sin” lead to mortal sin (CCC 1863).

“Mortal sin destroys charity in the heart of man by a grave violation of God’s law” (CCC 1855) and if “it is not redeemed by repentance and God’s forgiveness, it causes exclusion from Christ’s kingdom and the eternal death of Hell” (CCC 1861). 

Guilt of mortal sin requires three conditions (CCC 1857-1860): 1) the act must be of a grave matter, 2) a man must have full knowledge of the sinful nature of a thought or act, and 3) a man must completely consent to commit the sin.

Eternal Damnation results from dying in Mortal Sin

Men “who die in a state of mortal sin descend into Hell, where they suffer the punishments of Hell, ‘eternal fire’” (CCC 1035).  Many Catholic men live with grave sins that are unconfessed: the majority fail to go to weekly Mass, look at porn and are stuck in other types of grave sins. If they do these things knowingly and willingly, then they are at risk to die in a state of mortal sin.  

Many Catholic men are currently in grave danger of eternal damnation because they are guilty of mortal in and do not receive the Sacrament of Penance: most Catholic men fail to keep the obligation to go to Confession even once per year (CCC 2042) and very few Catholic men go to Confession at least once a month.

When a Catholic man falls into a state of mortal sin, the Holy Spirit withdraws support of the man and remains dormant until such time as the man is cleansed of mortal sin in the Sacrament of Penance; the man in mortal sin loses all the supernatural help of the Gifts of the Holy Spirit which makes him significantly more vulnerable to additional grave sins and less able to take on holy acts and grow in virtue.
