Today is Day 2 of Summer Day Camp @ St. Pat, I talked about Supernatural Revelation. God revealed Himself through Holy Scriptures. There are 46 Books in the O.T., and 27 Books in the N.T. Moses is a central figure in the O.T. One central message of the O.T. is that God is One. There is only One God. And one central message in the N.T. is that God is Three: Holy Trinity. In God there is One Nature & Three Persons.
Only God can make things our of NOTHING. Creation account in Genesis: day1 & day 4 correspond to each other, day 2 & day 5, and day 3 & day6. Human beings & Angels are the highest of God's Creation. Angels are purely spiritual, other creatures are purely material, but only human beings are both spiritual and material.
Angels and men have freedom to choose. The bad angels made the choice not to love God, and thus became devils. God send each of us a Guardian Angel. Our Guardian Angel helps us by 1) inspiring us to do good, 2) protecting us from harm, and 3) praying for/with us. I told the young people stories of Guardian Angels from the Lives of the Saints (e.g. St. John Bosco, St. Gemma Galgani, & St. Faustina Kowalska).
Later, we went to play @ the beach. We were having lots of fun. Many young people got wet and some buried themselves into sand.
