John Chrysostom
Catena Aurea · Lukasevangelium 9
Then he called his twelve disciples together, and gave them power and authority over all devils, and to cure diseases. And he sent them to preach the kingdom of God, and to heal the sick. And he said unto them, Take nothing for your journey, neither staves, nor scrip, neither bread, neither money; neither have two coats apiece. And whatsoever house ye enter into, there abide, and thence depart. And whosoever will not receive you, when ye go out of that city, shake off the very dust from your feet for a testimony against them. And they departed, and went through the towns, preaching the Gospel, and healing every where.
(Hom. 22. in Matt.) But after that they had been sufficiently strengthened by His guidance, and had received competent proofs of His power, He sends them out, as it follows, And he sent them to preach the kingdom of God. And here we must remark, that they are not commissioned to speak of sensible things as Moses and the Prophets; for they promised a land and earthly goods, but these a kingdom, and whatsoever is contained in it.
