Well, happy St. Patrick's day one day late. I make a big deal of St. Patrick's day for several reasons. One is that I've been to Ireland so it's a chance to get out the pictures and tell my kids about it. We get books from the library about St. Patrick and Ireland. We cook green treats like cookies or cakes. We cut out shamrocks. And we pretend fun things about leprechauns - for the last couple of years the wee ones have gotten to the children's breakfast cereal and turned their milk green when we weren't looking!
And, every year, I tell them St. Patrick's explanation of the trinity. According to legend, St. Patrick held up an Irish shamrock and said this is a picture of the trinity. Each petal represents one part of God - the Father, Son and Holy Spirit - all separate but connected. Who knows if St. Patrick actually did it, but it's one of the clearest explanations of three in one that I've heard. So either my kids will get it, or they'll wonder why they think of shamrocks whenever their Sunday school teachers mention the trinity!
