Pick a three leaf clover or use our coloring page to discuss the Holy Trinity. Did you know it is said that St. Patrick used a 3-leafed clover to explain the Trinity? When speaking with people he would bend down, pick a shamrock, and show it to them, as he explained how the three leaves are part of the one plant, and how similarly the three Persons, Father, Son, and Holy Spirit, are part of one God.
