The name of Jesus is not a magic incantation that causes demons to flee from before us. The seven sons of Sceva are an example of what can happen when people presume an authority they have not been given (Acts 19:13–16). Even Michael the archangel did not rebuke Satan in his own power but said, “The Lord rebuke you!” (Jude 1:9). When we start talking to the devil, we run the risk of being led astray as Eve was (Genesis 3:1–7). Our focus should be on God, not demons; we speak to Him, not them.

MORTAL SIN

BASIC R.C. BELIEF A serious offense against the law of God, called mortal because it renders the soul dead to sanctifying grace and makes it subject to the eternal punishment of Hell. The conditions that must be present for this sin to be mortal are: serious matter, sufficient reflection, full consent of the will.

Venial sin is a minor offense, and by committing it one does not lose sanctifying Grace, but will go to Purgatory because of unforgiven venial sin.

From THE SINS ARE FORGIVEN, by Francis Connell, C.SS.R., Imp. Francis Spellman. p. 28, “One who remains in sanctifying grace for any length of time … amasses an abundance of supernatural treasure. … But even one mortal sin suffices to deprive a person of this treasure.”

From FATHER SMITH INSTRUCTS JACKSON, page 77. “Father Smith: In closing this instruction I might note that by mortal sin we relinquish all past merit, but when the mortal sin is forgiven through the Sacrament of Penance, merit revives in proportion to the sincere and loving sorrow with which the sinner receives the Sacrament.”

POST VATICAN II The conditions necessary for mortal sin are causing some modern theologians to wonder if a person can commit a mortal sin, for if he reflected sufficiently, he would know the sin could send him to Hell, and he could never give full consent of his will. Therefore the conditions could not be met.
