The Place of Self-Denial on the WAY to Union with God
Tauler saith: "There be some men at the present time, who take leave of types and symbols too soon, before they have drawn out all the truth and instruction contained therein." Hence they are scarcely or perhaps never able to understand the truth aright. [For such men will follow no one, and lean unto their own understandings, and desire to fly before they are fledged. They would fain mount up to heaven in one flight; albeit Christ did not so, for after His resurrection, He remained full forty days with His beloved disciples. No one can be made perfect in a day. A man must begin by denying himself, and willingly forsaking all things for God's sake, and must give up his own will, and all his natural inclinations, and separate and cleanse himself thoroughly from all sins and evil ways. After this, let him humbly take up the cross and follow Christ. Also let him take and receive example and instruction, reproof, counsel and teaching from devout and perfect servants of God, and not follow his own guidance. Thus the work shall be established and come to a good end. And when a man hath thus broken loose from and outleaped all temporal things and creatures, he may afterwards become perfect in a life of contemplation. For he who will have the one must let the other go. There is no other way.]
Now be assured that no one can be enlightened unless he be first cleansed or purified and stripped. So also, no one can be united with God unless he be first enlightened. Thus there are three stages: first, the purification; secondly, the enlightening; thirdly, the union. [The purification concerneth those who are beginning or repenting, and is brought to pass in a threefold wise; by contrition and sorrow for sin, by full confession, by hearty amendment. The enlightening belongeth to such as are growing, and also taketh place in three ways: to wit, by the eschewal of sin, by the practice of virtue and good works, and by the willing endurance of all manner of temptation and trials. The union belongeth to such as are perfect, and also is brought to pass in three ways: to wit, by pureness and singleness of heart, by love, and by the contemplation of God, the Creator of all things.]
