My Catholic mother in law is shocked we read the Bible to my three year old, and have her do memory work.
I am a Missouri Synod Lutheran. I honestly don’t know when I started Sunday School as a kid, I was that young. My bride said she didn’t have any religious education outside the home till third or fourth grade.
Seems to me that is very odd in today’s culture. You will loose the kids by then.
I am very proud of your family. You have probably heard this, as a Lutheran, but Catholics if they attend Holy Mass daily, will hear pretty much the entire Bible every three years. Coupled with the Readings for each day, of course, is the homily, wherein the Sacred Scripture Reading is expounded upon. IF, you have a priest gifted with faith who is good at delivering a teaching homily.
So, Catholics should know their scripture when they hear it, and even know of it in its complete and particular contextual form, inclusive of its total mentions and references throughout the Bible, but not usually in the way of chapter and verse, which is quite helpful.
Children are most capable and generally undertaught. You respect their capabilities and feed them. That is ever so wonderful.
Sorry, I lost my ping to you. To #34.
