We are, therefore, about to found a school of the Lord's service, in which we hope to introduce nothing harsh or burdensome. But even if, to correct vices or to preserve charity, sound reason dictateth anything that turneth out somewhat stringent, do not at once fly in dismay from the way of salvation, the beginning of which cannot but be narrow. But as we advance in the religious life and faith, we shall run the way of God's commandments with expanded hearts and unspeakable sweetness of love; so that never departing from His guidance and persevering in the monastery in His doctrine till death, we may by patience share in the sufferings of Christ, and be found worthy to be coheirs with Him of His kingdom. (Prologue, Rule of St. Benedict)
