For those who disparage our modern holy fathers:

A man who does not express desire to link himself to the latest of the saints (in time) in all love and humility owing to a certain distrust of him, will never be linked with the preceding saints and will not be admitted to their succession, even though he thinks he possesses all possible faith and love for God and for all His saints. He will be cast out of their midst, as one who refused to take humbly the place allotted to him by God before all time, and to link himself to that latest saint (in time) as God had disposed.
St. Symeon the New Theologian

Self-Interpreting Scripture?

Spiritual knowledge is like a house built in the midst of Greek and worldly wisdom, in which house, like a tightly locked trunk, there is the knowledge of the divine Scriptures, and the unutterable treasure hidden in this knowledge of the Scriptures, that is, Divine grace. Those who enter this house cannot see this treasure if the trunk is not opened for them, but this trunk cannot be opened by any human wisdom. This is why people who think in a worldly way do not know the spiritual treasure which lies in the trunk of spiritual knowledge, And just as someone who lifts this trunk on his shoulders cannot by this alone see the treasure which is inside, so also even if someone were to read and learn by heart the divine Scriptures, and could read them all like a single psalm, he cannot by this alone acquire the grace of the Holy Spirit, which is hidden in them. For just as what is hidden in the trunk cannot be revealed by the trunk itself, so also what is concealed in the divine Scriptures cannot be revealed by the Scriptures themselves.
St. Symeon the New Theologian

The task of modern Cross bearers

In times past, when heresies prevailed, many chose death through martyrdom and various tortures. Now, when we through the grace of Christ live in a time of profound and perfect peace, we learn for sure that cross and death consist in nothing else that the complete mortification of self-will. He who pursues his own will, however slightly will never be able to observe the precepts of Christ the Saviour.
