Gregory of Nazianzus
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.
(Orat. ii. 69.) Now in sending His disciples to preach, our Lord enjoined many things on them, the chief of which are, that they should be so virtuous, so constant, so temperate, and, to speak briefly, so heavenly, that no less through their manner of living than their words, the teaching of the Gospel might be spread abroad. And therefore were they sent with lack of money, and staves, and a single garment; He accordingly adds, And he said to them, Take nothing in the way, neither staves.
