3 Then, brethren, this I would say, this I do say, this if I might I would not leave unsaid: Let there be in you now these works, now those, according to the time, according to the hours, according to the days. Are you always to be speaking? Always to keep silence? Always to be refreshing the body? Always to be fasting? Always to be giving bread to the needy? Always to be clothing the naked? Always to be visiting the sick? Always to be bringing into agreement them that disagree? Always to be burying the dead? No: but now this, now that. These things are taken in hand, and they stop: but that which as emperor commands all the forces within neither has beginning nor ought to stop. Let charity within have no intermission: let the offices of charity be exhibited according to the time. Let “brotherly love” then, as it is written, let “brotherly love continue.”
