‘Wine makes glad the heart of man' (Ps. 104:15). But you who have professed sorrow and grief should turn away from such gladness and rejoice in spiritual gifts. If you rejoice in wine, you will live with shameful thoughts and distress will overwhelm you.
One of the most mysterious anticipations of the Orthodox Church is the contemplation of the 'Protecting Veil of the Mother of God,' of Her constant standing in prayer for the world, surrounded by all the saints, before the throne of 'God. 'Today the Virgin stands in the Church and with hosts of saints invisibly prays to God for us all; angels and high priests worship; apostles and prophets embrace each other-it is for us that the Mother of God prays unto the Eternal God!' Thus the Church remembers the vision which was once seen by St. Andrew, the fool for Christ's sake. And that which was then visibly revealed remains now and will stand for all ages. The 'Contemplation of the Protecting Veil' of the Mother of God is a vision of the celestial Church, a vision of the unbreakable and ever-existent unity of the heavenly and the earthly Church.
To wage war only with the sins that make their appearance as actual deeds would be just as unsuccessful as cutting down weeds in a garden instead of digging them up at the root and throwing them out. Sins appear as inevitable outgrowths from their roots, the passions of the soul.
Even a pious person is not immune to spiritual sickness if he does not have a wise guide -- either a living person or a spiritual writer. This sickness is called prelest, or spiritual delusion, imagining oneself to be near to God and to the realm of the divine and supernatural. Even zealous ascetics in monasteries are sometimes subject to this delusion, but of course, laymen who are zealous in external struggles (podvigi) undergo it much more frequently. Surpassing their acquaintances in struggles of prayer and fasting, they imagine that they are seers of divine visions, or at least of dreams inspired by grace. In every event of their lives, they see special intentional directions from God or their guardian angel. And then they start imagining that they are God's elect, and often try to foretell the future. The Holy Fathers armed themselves against nothing so fiercely as against this sickness -- prelest.
