I was taught in the Seminary that if you fail to study both LIVES OF THE SAINTS and DOCTRINE, you will end up lopsided and in error.
No doctrine? You will be looking for exceptions, miracles, visions everywhere, and end up who knows where. You will have no grounding in doctrine, which teaches us the Ordinary path.
No Lives of the Saints? You will be a legalist Pharisee, considering only the dry aspects and duties of Catholicism and forget that God does sometimes make exceptions, miracles, etc. There is a Supernatural and a place for the Extraordinary.
Both are required for a balanced Catholic life.
For example, recall the saint who saw a condemned man, a criminal, heading for his execution. The man was not well disposed either; he might have been cursing or otherwise obviously "indisposed" for a holy death on the way to his execution. But this saint fervently prayed to God for his soul, and even took on his temporal punishment as penance, and God answered her prayer. The man was miraculously converted on the gallows. THAT is Charity, the love of God, true Catholicism.
The criminal in question was 100% guilty, external forum wise, he definitely "belonged in Hell" as you put it. But did the saint (St. Therese?) relish in that thought of God's justice? NO. Like Christ, she "willed not the death of the sinner, but that he be converted and live." And talk about putting one's money where their mouth is! She suffered greatly for this one soul. Like Christ would do.
And here's a sobering thought for all of us, with Lent 2 weeks from today: if you aren't ready to do the same, right now, then you aren't ready to enter heaven. Best case, if you died you would have to go to purgatory for purification. Even if you have zero sins on your soul or habitual sins, just the fact you are not in the Unitive Way means your soul is NOT ready to see God. There are undue attachments to this world, to your own will, to comfort, possessions, security, lawful pleasures, etc. which hinder your soul's ascent to Heaven.
Talking to myself as well as everyone else on the forum, of course. Just wanted to mention this as a sort of PSA, so we could all benefit more this Lent.
