We come to the wedding banquet of heaven by way of humility and charity.
He is revealing the way of the kingdom, in which the one who would be greatest would be the servant of all
He showed us, humbling Himself to come among us as a man (see Philippians 2:5-8), as one who serves, as the bearer of glad tidings to the poor
the Father has shown us down through the ages - filling the hungry, sending the rich away empty, lifting up the lowly, pulling down the proud
We are to live humbly, knowing we are are not worthy to receive from His table
We are to give alms, remembering we were ransomed from sin by the price of His blood
if we are kind to those who can never repay us, we will atone for sins, and find blessing in the resurrection of the righteous.
In the Mass, we enter the festal gathering of the angels and the firstborn children of God, the liturgy of the heavenly Jerusalem in which Jesus is the high priest, the King who calls us to come up higher
