Today is also the anniversary of my Baptism and in our community we celebrate Baptism anniversaries in a special way. It is the day when I became a child of God. So this evening at Evening Prayer I will renew my Baptism promises (to gain a plenary indulgence) and that will be followed by a fine dinner and some small gifts. The Sisters will take turns encouraging me about the way they see me growing in my spiritual life. (My faults and weaknesses are never mentioned!)
Perhaps that is why I love this feast day so much and why I love my Guardian Angel so much. Padre Pio had a very significant relationship with his Guardian Angel. And Padre Pio is a saint!
