Someone mentioned having your husband start independent bible studies at home using the bible alone. Here is a good outline to use.

You also ask for suggestions on how you could begin to celebrate the holidays - why not try doing some holiday baking that matches your Cultural Heritage. For instance, Germans, Swedish, and Norwegians all have very distinct cookies and other backed holiday recipes. Search the internet for information and holiday recipes. Here are just a few I came up with.

If you want to begin making Christmas memories this year, you could begin by having your kids bake and make decorations that matched your cultural heritage.
Hope this helps,
