Theophylact of Bulgaria
Since He commissioned His disciples to be instructors throughout the world, He appropriately admonishes them not to emulate the Pharisees in their desire for recognition, their pursuit of prominence, or their general inclination towards worldly matters and human approval. It is characteristic of those who seek to flatter others they encounter and crave a favorable perception of themselves, often using it as a method of financial gain, to be highly attentive to greetings in public places.
