God understands and accepts our feeble attempts at worship. What a beautiful thing to experience communion on an extraterrestrial site! He is Lord of all creation not just our small planet. I am very moved reading about this and a little jealous. God is wondrous beyond our imagination.
I wonder what if the priest is in a state of sin. Does the sacrament become invalid? When your access to God is dependent upon a mortal man what if that man is like many priest in rebellion with the church. Is your confirmation, communion, confession, marriage, etc. all invalid?
