The belly when filled with all kinds of food gives birth to seeds of wantonness, nor can the mind, when choked with the weight of food, keep the guidance and government of the thoughts. For not only is drunkenness with wine wont to intoxicate the mind, but excess of all kinds of food makes it weak and uncertain, and robs it of all its power of pure and clear contemplation. The cause of the overthrow and wantonness of Sodom was not drunkenness through wine, but fullness of bread. Hear the Lord rebuking Jerusalem through the prophet. 'For how did thy sister Sodom sin, except in that she ate her bread in fullness and abundance?' (Ezek. xvi. 49)
Without podvig there is altogether no true Christianity, that is to say, Orthodoxy. See what Christ, the First Ascetic, Himself clearly says; 'Whosoever will come after Me, let him deny himself, and take up his cross, and follow Me' (Mark 8:34). The true Christian, the Orthodox Christian, is only he who strives to emulate Christ in the bearing of the cross and is prepared to crucify himself in the Name of Christ. The holy Apostles clearly taught this. Thus the Apostle Peter writes: 'If when you do well and suffer for it, ye take it patiently, this is accepted with God. For even here unto were ye called, because Christ also suffered for us, leaving us an example, that we should follow his steps' (I Pet. 2:2-21). In precisely the same way the holy Apostle Paul says repeatedly in his epistles that all true Christians must be ascetics, and the ascetic labor of the Christian consists of crucifying himself for the sake of Christ: 'They that are Christians have crucified the flesh together with the passions and lusts' (Gal. 5:24). A favorite expression of St. Paul is that we must be crucified with Christ that we might rise with Him.
During the divine services, and at the very moment when the Mysteries (e.g., Holy Communion) are being accomplished, this vile enemy often blasphemes the Lord and the holy Sacrifice that is being consecrated. Wherefore, we clearly learn that it is not our soul that pronounces these unspeakable, godless and unthinkable words within us, but the God-hating fiend who fled from Heaven for uttering blasphemies against the Lord there too, as it would seem. For if these shameless and disgraceful words are my own, how could I worship after receiving the Gift? How can I praise and revile at one and the same time?
One should not ponder divine matters on a full stomach, say the ascetics. For the well-fed, even the most superficial secrets of the Trinity lie hidden.
When the intellect begins to advance in love for God, the demon of blasphemy starts to tempt it, suggesting thoughts such as no man but only the devil...could invent. He does this out of envy, so that the man of God, in his despair at thinking such thoughts, no longer dares to soar up to God in his accustomed prayer. But the demon does not further his own ends by this means. On the contrary, he makes us more steadfast. For through his attacks and our retaliation we grow more experienced and genuine in our love for God.
If a person swallows too much food, he is inviting impure thoughts. If he mortifies the stomach, he is creating pure thoughts. Often a lion if it is caressed becomes domesticated, whereas the more you coddle the body, the more it goes wild.
Blasphemy brings the wrath of the Lord upon the rulers, the armies and the nations… the blasphemers are the most impious and sinful of all…It is an absolute need that the wound of blasphemy be completely wiped out from the Nation in order for it to have good fortune, to be glorified and uplifted.
No one in the face of blasphemous thoughts need think that the guilt lies within him, for the Lord is the Knower of hearts, and He is aware that such words and thoughts do not come from us but from our foes.
An Athonite elder said, 'Blasphemous thoughts are like airplanes that annoy us, against our will, with their noise, and we are powerless to prevent them. The heavy anti-aircraft battery is psalmody, because it is both prayer to Christ and disdain for the devil.'
It is not food that is evil but gluttony; not childbearing but fornication; not money but cupidity; not glory but vainglory. If this be so there is no evil in anything that is, except wrong use, which results from our mind neglecting to cultivate our nature (the powers of the soul, and their right direction).
When we stand in prayer, those unclean and unspeakable thoughts (blasphemy) assail us; but if we continue praying to the end, they retire at once, for they do not fight those who stand up to them.
