Sabbath Mode?

While researching new-to-us ovens on craigslist as part of our on-going kitchen remodel I came across something else new to me; a feature called "Sabbath Mode" for kosher kitchens.
This is what I found:

"One of the Sabbath laws is that raw food may not be cooked on the Sabbath, but food which was already cooked beforehand may be kept warm until mealtime. On holidays, food may be cooked fresh, but turning the flame on is problematic. In the past, both of these could be accomplished simply by lighting a flame before the day begins, and using its heat over the course of the day. In recent decades, however, appliance manufacturers have instituted a safety feature which automatically shuts off the heat after a number of hours. This renders the appliance useless for those who observe these religious laws.

The key features of Sabbath mode ovens are that it disables the standard six- or twelve-hour cutoff and all lights and displays are disabled, so that no visible activity takes place when the oven door is opened. "

If you are as nerdy as me and want to know more, click here and here.

However, my interest here is not so much the law that Orthodox Jews follow, but that without this feature in everyday kitchen staples, a law, which beautifully allows it's followers to honor their faith might appear completely unreasonable and out-dated.

Sundays can be hard. I guess this is because Chuck and I have yet to really cement our family's list of Sunday do's and dont's. Generally, we are a no TV on Sundays kind of family, but with varying Sunday obligations and Chuck's irregular work and sleep schedule, occasional classic movie viewing, mostly old musicals, are a small part of passing the day now and then for us(not to mention a little Extreme Home Makeover) . I think the biggest problem we have, is that our don't list is much much larger than our do list. I have heard of people making Sunday boxes filled with special activities just for that day but have yet to assemble one; mostly because I am unsure of what to put in one. I would love to hear what Sabbath Mode is for others, especially those with children. Because, as far as I know, this is one of those areas where there are no strict guidelines, I hope it can be discussed without judgmental attitudes. I have some friends who make it a point to never travel on the Sabbath, and others who love to get away together when church callings allow and I respect both ideas. I just want to know what works for you and helps your family feel closer to God and each other, not what some might feel is the ultimate in holy rolling.
