Re: Church Preschools
I never went to preschool but my parents sent me to Catholic schools from grade 1 and onwards. When I was growing up, there weren’t any Islamic schools closeby (in fact I don’t know if they even existed…this was in 1990); my parents reasoning was that public schools were substandard…and at least I’d be in a religious environment, even if it was Christian and not Islamic which was better than being in public school.
From grade 1 through 8 the focus was on the life of Jesus and Christian teachings. There would be monthly mass + during their holidays (Christmas, Easter, etc)…I enjoyed those cz that would take us out of class for the day..lol. I was never required to participate (at the end of mass, everyone lined up to receive the blood and bread of Christ (which was really erm wafers and I think…not sure at all..wine or juice), except just to be there. Everyday we’d say a prayer and the pledge of allegiance…and yes I do know 2 of the Catholic prayers.
I was hte only non-Christian/non-black/non-Hispanic student and tbh I was never made to feel like crap because of those things by any of my teachers or fellow students. (I was awkward and felt out of place, but not because of these two things). I did well in religion class, but only because I was a good student for the most part.
Now high school was very different–first it was an all girls school and not coed like elementary school; also, there was a bigger variety of races there–white/Italian, desi, arabs etc. Again, never felt out of place for being Muslim/Pakistani.
Curriculum wise–the first year was practically a continuation of what I’d learned in elementary school.
Second year focused on morality and ethics. It was from a religious viewpoint but they were lessons that transcended religion, like S02 mentioned.
Junior year was about social justice. One of our projects was trying to feed/support a family of 4 on 25K a year for a month…it wasn’t a heavy emphasis on religion but about charity work, and helping others and stuff.
Senior year was divided into Death and Dying (which actually discussed death and funerals throughout all religions, including islam) and Christian Womanhood (one of our assignments was to plan our own weddings and come up with a budget and all).
Now the high school stuff was very interesting because the focus was more on being a good/knowledgeable person…things that anyone of any religion could appreciate.
Also,
Since you’re in this part of the country, I wouldn’t worry too much; growing up I never faced any weirdness about being Muslim/Pakistani, although I don’t know how different that would be now.
PS, I have never ever had any desire to convert to Catholicism.
