I was raised in a nonreligious household. Not anti-religious, or active athiest, simply nonreligious. Religion simply was not a factor.
It wasn’t by intentional avoidance, it simply wasn’t a topic that often came up for discussion.
Ben Hur was just a movie, Chistmas was just a holiday, Passover was an obscure little word you’d see on the occasional calendar.
Both my parents were nonreligious- again, not an intentional avoidance, it simply wasn’t a pastime, hobby or occupation that anyone partook in.
Churches were just another building you saw in town- as a kid it was like the Real Estate agents, the city planning office, or the courthouse: you rarely, if ever, went there, and when you did, there were no kids or toys there, so what reason did a kid have to be there?
My parents were big on the “look it up” school of thought, when it comes to answering the Great Questions. We always had large numbers of books: unabridged dictionaries, entire Britannica sets, specialized encyclopaedia like Childcraft and a Brit How it Works set, the usual books like Huckleberry Finn and Treasure Island, even works by Tolstoy.
We had books on car repair, metal casting, stained glasswork and electrical theory. Illustrated kids books that demonstrated esoterics like Archimedes’ principle and the Bernoulli Effect. I fondly recall a Mr. Wizard volume that showed a kid how to make an electromagnet, or a Leyden Jar, or a compound wet-cell battery.
When one of us kids had a question- why is the sky blue? Where do tadpoles come from?- the usual reply was “look it up”. They’d steer us toward the right volume, perhaps, occasionally help us find the topic in question, but often the search itself was as much an educational exercise as learning the quested tidbit itself.
As near as I can recall, the only time the process led to any frustration or anger was when we had no reference for the topic, which happened often enough, even with our copious library.
By the time I was old enough to hear of religion and God and the purpose of churches and such, the desire to learn was well ingrained, and the skill to search for the data was growing. I remember clearly an occasional question like “Why is Easter on this particular Sunday?” or “what is ‘jehovah’?” and looking it up.
The Britannicas in particular were reasonably decent, even back then, with presenting the god-figures and religious icons in a neutral light- like mentioned above, “these people believe this, so…” or “the inhabitants of XXXX tended to believe in So-and-So…” as opposed to having, say, “God is the Creator of All…” etc and so on under the listings.
I was allowed to make up my own mind, free of superstition, mythology or religious propaganda, and I found religion in general wanting.
Again, it wasn’t an intentional avoidance, it simply wasn’t something that held any appeal. Go to church? What for? Pray? Why?
I suggest raising the child with as much educational matter as she can handle, but don’t force more than that on her. When she asks why the sky is blue, say “let’s look that up and see”, whether you use a dusty old encyclopedia or Google. The act of ‘looking it up’ is as educational as the thing being looked for.
