He will take you however you come, of course.
As for what will happen at the Mass, … if our eyes could only see !
Heaven coming to Earth is a good description,
St Francis said it as well as anyone:
Let humanity kneel in fear, let the whole universe tremble, and let heaven rejoice when Christ the Son of the Living God is on the altar in the hands of the priest!
O wonderful ascent, O stupendous ascent! O sublime humility! O humble sublimity, that the Lord of the Universe, God and Son of God, should humbly hide himself, for our salvation, in what seems to be only a small piece of bread! Look, then, upon the humility of God! And pour out your hearts before Him. Humble yourselves that He might exalt you. Hold back nothing of yourselves for yourselves, that He may receive your all who gave His all for you!
Saint Francis of Assisi
Letter to the Whole Order
