So then He sent reapers, no sowers. The reapers went where the Prophets had preached. Read the account of their labours: they all contain prophecy of Christ. And the harvest was gathered on that occasion when so many thousands brought the prices of their possessions, and laid them at the Apostles’ feet; relieving their shoulders from earthly burdens, that they might follow Christ. Yea verily, and from that harvest were a few grains scattered, which filled the whole world. And now ariseth another harvest, which will be reaped at the end of the world, not by Apostles, but by Angels. The reapers, He says, are the Angels. (Mat. 13)
