13 You who have been enrolled have become sons and daughters of one Mother. When you have come in before the hour of the exorcisms, let each one of you speak things tending to godliness: and if any of your number be not present, seek for him. If you were called to a banquet, would you not wait for your fellow guest? If you had a brother, would you not seek your brother's good?
Afterwards busy not yourself about unprofitable matters: neither, what the city has done, nor the village, nor the King, nor the Bishop, nor the Presbyter. Look upward; that is what your present hour needs. Be still, and know that I am God. If you see the believers ministering, and showing no care, they enjoy security, they know what they have received, they are in possession of grace. But you stand just now in the turn of the scale, to be received or not: copy not those who have freedom from anxiety, but cherish fear.
