“There are many who have self-control, which do keep themselves from lusting after things outward … who long with intense home-sickness for their Fatherland which is in heaven”

From the Holy Gospel according to St. Matthew
Matt 25:1

At that time, Jesus said to His disciples: The Kingdom of heaven shall be likened unto ten virgins, which took their lamps, and went forth to meet the Bridegroom and the Bride. And so on. 

The body of every man doth consist of five senses, and five being doubled, is ten. Forasmuch, therefore, as the whole body of the faithful doth consist of two sexes, the Holy Church is likened unto ten virgins. And forasmuch as in the Church the good are for the present mingled with the bad, and the reprobate with the elect, it is rightly said that, of the ten virgins, five are wise and five are foolish. There are many who have self-control, which do keep themselves from lusting after things outward, whose hope beareth them to things inward, who chastise the flesh, who long with intense home-sickness for their Fatherland which is in heaven, who seek an eternal reward, and who will not to receive for their labours the praise of men. These are they who reckon their glory, not in the mouths of men, but in the testimony of their own conscience. And many there be likewise who afflict the body by self-control, and yet who seek for their self-control applause from men.
