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
