When we have the ability to research and learn–truth from untruth—can we really use the excuse that we have misplaced obedience—an follow one who leads to untruth.
From St. Louis de Montfort: True Devotion To the Blessed Virgin Mary, No. 228
Of Judgment, and the Punishment of Sinners In all things look to the end; and how thou wilt stand before that strict Judge (Heb. 10:31) to whom nothing is hid, who is not appeased with gifts, nor admitteth excuses, but will judge according to right. O wretched and foolish sinner, who sometimes art in terror at the countenance of an angry man, what answer wilt thou make to God who knoweth all thy wickedness (Job 9:2)! Why dost thou not provide for thyself (Luke 16:9) against the day of judgement, when no man can be excused of defended by another, but every one shall be a sufficient burden for himself!
