Slaying Dragons: What Exorcists See & What We Should Know (Slaying Dragons Series Book 1)

When the father commits a mortal sin of a certain sort, like pornography, he is now vulnerable to diabolical influence. If a demon comes in at that moment, he can corrupt the whole family, since he entered through the head of the family.[378] The demon can also remain and be passed down through successive generations.

Sin involves rejecting the commands of God and, as a consequence, placing ourselves out of the proper structure of authority and in a state where we are vulnerable to evil.

Fr. Ripperger describes how rational creatures stand in one of the fivefold relationships with God’s mercy: Angels are not in need of God’s mercy; demons make no claim to God’s mercy, and have cut themselves off from it; the damned in Hell had it at one point but rejected it; saints in Heaven have it completely; and men on earth are at least partia

We must remember – the demons want us to fall into sin, and to die in a state of sin, and then to be subjected to them in Hell. We must know and accept this and do the work to avoid letting them win.
