When Jesus and his disciples are said to be in the world but not of the world, the meaning is clear enough. Although they live in the world they are not worldly, they do not subscribe to the present values and standards of the world.
--Albert Nolan, O.P.

The foundation of our way to God is to advance on the way of life with great patience, humility, poverty of spirit, and meekness. All these lead us to justice--and by justice, we mean the Lord himself.
--Macarius (c. 302-392)
