Theophylact of Ohrid
Catena Aurea · Lukasevangelium 12
Fear not, little flock; for it is your Father’s good pleasure to give you the kingdom. Sell that ye have, and give alms; provide yourselves bags which wax not old, a treasure in the heavens that faileth not, where no thief approacheth, neither moth corrupteth. For where your treasure is, there will your heart be also.
By the little flock, our Lord signifies those who are willing to become His disciples, or because in this world the Saints seem little because of their voluntary poverty, or because they are outnumbered by the multitude of Angels, who incomparably exceed all that we can boast of. The name little our Lord gives to the company of the elect, either from comparison with the greater number of the reprobate, or rather because of their devout humility.
