From time to time I have heard… always from liberals… that children shouldn’t be made to memorize when they learn. They claim that, because children don’t "understand" what they are memorizing, memorizing is counterproductive.
The collapse of Catholic education was accelerated by, inter alia, the move away from memorization.
Once upon a time I was called in to a hospital where a man in in his last minutes. He had a hard death. The old man’s daughter, fallen away, was very bitter, very angry and she unloaded on God by unloading on me.
I tried to impress on her that he had lived a good life in an earthly way and now his life would continue, but in another and better way.
She was having nothing of it. She was focused on the bad experience as he was dying.
She eventually fumed "Why did your God do this to him? Make any of us at all if this is what happens?"
I responded: "Why did God make you?"
She paused. The light bulb went on.
"God made me to know Him, to love Him, and to serve Him in this world, and to be happy with Him for ever in heaven."
Someone had taken the time to drill that into her, and it was still there.
What had been buried for decades, memorized as a child long before she could "understand" what it meant, was there and ready for her in the moment she needed it.
Yes, I am in favor of children memorizing things.
