We have always saved 3 small gifts and set them aside for giving out on three kings day... or 12th night. I also hide a gold coin in a Buche de Noel or yule log which we eat on three kings day... the person who receives the coin in their piece is King of the year!
In our house, Santa brings 3 gifts for each child. All other gifts are from family. The 3 gifts are to tie Santa back to the reason for the season.
Why is Jan. 6 called Three Kings Day? The Bible doesn’t say the number of wise men who visited Jesus, and the Bible doesn’t say that the wise men were kings. People assume that there were three wise men, since they gave three gifts. My dad (a former ELCA pastor who attends an LCMC church) said that, when he was in seminary, he learned that there were 15-18 wise men.
