YOUCAT Question n. 69 - Part II. Are we compelled to sin by original sin?

(Youcat answer - repeated) No. Man, though, is deeply wounded by original sin and is inclined to sin. Nevertheless, with God’s help he is capable of doing good.    

A deepening through CCC

(CCC 1264) Yet certain temporal consequences of sin remain in the baptized, such as suffering, illness, death, and such frailties inherent in life as weaknesses of character, and so on, as well as an inclination to sin that Tradition calls concupiscence, or metaphorically, "the tinder for sin" (fomes pectin); since concupiscence "is left for us to wrestle with, it cannot harm those who do not consent but manfully resist it by the grace of Jesus Christ" (Council of Trent (1546): DS 1515). Indeed, "an athlete is not crowned unless he competes according to the rules" (2 Tim 2:5).     

Reflecting and meditating 

(Youcat comment) In no single case are we obliged to sin. In fact, however, we sin again and again, because we are weak, ignorant, and easily misled. A sin committed under compulsion, moreover, would be no sin, because sin always involves a free decision.

(CCC Comment)

(CCC 2515) Etymologically, "concupiscence" can refer to any intense form of human desire. Christian theology has given it a particular meaning: the movement of the sensitive appetite contrary to the operation of the human reason. The apostle St. Paul identifies it with the rebellion of the "flesh" against the "spirit" (Cf. Gal 5:16, 17, 24; Eph 2:3). Concupiscence stems from the disobedience of the first sin. It unsettles man's moral faculties and, without being in itself an offense, inclines man to commit sins (Cf. Gen 3:11; Council of Trent: DS 1515). (CCC 985) Baptism is the first and chief sacrament of the forgiveness of sins: it unites us to Christ, who died and rose, and gives us the Holy Spirit.
