First Reading Wisdom 18.6-9
The night of the deliverance from Egypt was made known beforehand to our ancestors, so that they might rejoice in sure knowledge of the oaths in which they trusted.
The deliverance of the righteous and the destruction of their enemies were expected by your people. For by the same means by which you punished our enemies you called us to yourself and glorified us.
For in secret the holy children of good people offered sacrifices, and with one accord agreed to the divine law, so that the saints would share alike the same things, both blessings and dangers; and already they were singing the praises of the ancestors.
Psalm 33
R. Blessed the people the Lord has chosen as his heritage.
Rejoice in the Lord, O you righteous. Praise befits the upright. Blessed is the nation whose God is the Lord, the people whom he has chosen as his heritage. R.
Truly the eye of the Lord is on those who fear him, on those who hope in his steadfast love, to deliver their souls from death, and to keep them alive in famine. R.
Our soul waits for the Lord; he is our help and shield. Let your steadfast love, O Lord, be upon us, even as we hope in you. R.
Second Reading Hebrews 11.1-2, 8-12
Brothers and sisters: Faith is the assurance of things hoped for, the conviction of things not seen. Indeed, by faith our ancestors received approval.
By faith Abraham obeyed when he was called to set out for a place that he was to receive as an inheritance; and he set out, not knowing where he was going. By faith he stayed for a time in the land he had been promised, as in a foreign land, living in tents, as did Isaac and Jacob, who were heirs with him of the same promise.
For Abraham looked forward to the city that has foundations, whose architect and builder is God. By faith Sarah herself, though barren, received power to conceive, even when she was too old, because she considered him faithful who had promised.
Therefore from one person, and this one as good as dead, descendants were born, “as many as the stars of heaven and as the innumerable grains of sand by the seashore.”
Gospel Luke 12.35-40
“Be dressed for action and have your lamps lit; be like those who are waiting for their master to return from the wedding banquet, so that they may open the door for him as soon as he comes and knocks. Blessed are those slaves whom the master finds alert when he comes; truly I tell you, he will fasten his belt and have them sit down to eat, and he will come and serve them. If he comes during the middle of the night, or near dawn, and finds them so, blessed are those slaves.
“But know this: if the owner of the house had known at what hour the thief was coming, he would not have let his house be broken into. You also must be ready, for the Son of Man is coming at an unexpected hour.”
