The "Christian" part has been pretty stable. Even though my Mormon upbringing was light on Jesus, I find his example and teachings compelling. One reason is that I see them as an antidote to authoritarianism and tribalism, which I think are the two aspects of human nature most likely to destroy us all and everything we've built.
I came to the jarring realization a couple of months ago that a vital part of the antidote is something I don't really believe in: grace. To be more precise, I believe in humans practicing self-compassion and self-forgiveness and extending the same grace to others. I don't believe in the need for God to extend grace to humans, but for people who believe in God this seems to be more or less equivalent to the grace I do believe in.
I think believing in either secular or religious grace is essential for liberation from religious social control. I'm sure most of us have been caught up before in the endless cycle of sin, shame and repentance that burdens believers and entangles them in their religions. I was until I discovered religious grace years ago. Grace allowed me to stop judging myself, stop judging others, stop worrying about institutional judgment, disbelieve the bullshit claim that personal purity has anything to do with blessings from God, disbelieve in Satan, think of unbelievers as equals, let go of certainty, wonder whether Mormonism had lost its way in following the gospel of Jesus Christ, question other Mormon truth claims, and finally get angry with God long enough to question whether Mormon doctrine about something as basic as God was true. It couldn't be true, so I fell.
Finding grace made me happier and mentally healthier in the church, and ultimately allowed me to find more truth and freedom out of it - though the latter came with profound grief. The Lord gave, and the Lord hath taken away; blessed be the name of the Lord. Also, as my vicar friend said to me last week, you can't be remade without first getting nailed to a cross.
Anyway, I've now given a Family Home Evening lesson on salvation by grace to my believing family. Critically, my wife was on board, having walked down the path of grace with me years ago. I started by giving my belief label of the day ("agnostic Christian") and finding common ground with my kids. Then we talked about three distinct doctrines of salvation taught in the LDS church.
Here's how the whiteboard ended up:

(The drawings on the bottom are from my youngest daughter dealing with math angst the next day.)
These three doctrines of salvation differ primarily in what's required to be saved. All are taught in the LDS church, sometimes by the same speaker in the same talk. It's really confusing. Others are taught, but IMO these are the most representative. The first one is salvation by grace. Each doctrine is unnamed (I didn't want to dignify the second two with names), and listed with where it's taught, what's required for salvation, when salvation happens, and worries related to it.
Points I made sure to cover:
- In the BoM, salvation means instant and total purity before God, as soon as you ask and are willing to keep the commandments. (Its consistency on this point is shocking.) Salvation is taught similarly in the New Testament - I think the biggest exception is the epistle of James.
- I gave them answers to the question, "If you're saved by grace, why would you do anything good?" by listing it as a worry. Also, it's the only question in the worry column with actual answers (in red). The other two questions in that column are unanswerable, leading to a lifetime of anxiety.
- I grew up with doctrine #3, moved to #2, and then to grace. I talked about how the others had partly caused depression once.
- I said this: "All three of these doctrines of salvation are taught in the scriptures and in church, and they can't all be true together, which means we get to choose one. Which do you think would be healthiest for our family?"
- Of these three doctrines of salvation, grace is taught least often at church.
- DW loved it.
- DD1 (18) was initially apprehensive because I was teaching. She was surprised that other doctrines besides salvation by grace are taught. I think she picked up on discussions between me and DW years ago when we were discovering it, which her younger siblings missed out on. She then filtered out everything she heard that didn't support salvation by grace.
- DS1 (16) appreciated having the confusing discourse at church finally sorted out. (He's a very logical thinker.) I think he also might have started feeling a little salty about having to refrain from passing and taking the sacrament over P&M last year, too.
- DD2 (13) said her mind is now blown. She also appreciated having the confusing discourse sorted out.
- DD3 (11) is probably too young to understand the significance of the entire discussion.
- I didn't try to reconcile all of the doctrines because I find no reason to try to make every GA correct. The closest we got was DW bringing up grace-affirming or grace-neutral ways to understand supporting scriptures for the non-grace doctrines.
- I requested that my family choose the healthiest one. I would have presented them as personal options before, or only taught salvation by grace.
- I classified GAs by the doctrines they seem to believe in. Uchtdorf plainly believes in grace. Holland seems to vacillate between grace and #2. Eyring is probably #2. Oaks and Nelson seem to be hardline #3.
- I mentioned that worthiness interviews are most consistent with doctrine #3.
