but I like what you have to say, ed!)
This is certainly a question that I have grappled with from the time I started writing in my teen years. I majored in Creative Writing in a mostly-secular English department, at a secular state university.
Many of my English professors (and other professors) were people who were raised Catholic and considered themselves to have “outgrown” Catholicism. This was less than two decades after the Vietnam War and social upheavals in other areas (radical feminism, contraception and “free love,” etc.). Although these problems certainly weren’t new at that time, as I have since realized. :nope:
Anyhow, I have written sci-fi, general fiction and poetry, and here lately started working on Catholic non-fiction and Catholic romance. Someday I’d like to write “cozy” murder mysteries if I can figure out how to plot them.

I have read books across a wide range and when I was younger in my own stumbling attempts to write, I was probably more liberal in the name of “realism” than I would be now . . .
But there is a certain level of believability that you have to attain, and there’s where you have to walk a fine line. You don’t want to glamourize sin. We live in a world where “extreme” and “irreverent” are compliments. So how do you manage not to glamourize sin and jaded attitudes?
I would say by avoiding graphic descriptions of violence or sex, and profanity in dialogue as much as possible. Or condoning adultery in the name of romance, or cheating in the name of creating an “antihero” figure. Reading great literature from times when not all the stuff that’s allowed in bestsellers these days would be one way. Maybe even reading a few of the bestsellers - with discernment - to see what’s “too much information” or “over the top.”
And when you have a sense of which direction you want to take your writing - what genre you want to write in, and what your themes are and how you’ll make your writing illustrate those, then you have to try and figure out how to be subtle. Have the lessons the characters learn, the realizations they discover, grow out of who they are and what happens - in a natural-seeming way. If you are too blatant about the “morality tale” the reader will feel hit over the head, but if you engage the reader and carry them along with the characters on a journey of discovery, they will be like “Yesss!” :newidea:.
I extend to you my best wishes for success, along with this invitation
