The vainglorious man is an idolator, although he is called a believer. He thinks that he is honoring God, but in actual fact he is pleasing not God, but men.

Venerable John of the Ladder

Sometimes undertakings good in appearance lead to their ac-complishment for the sake of glory and human praise, but in God's sight this is equal to untruth, thievery and other sins.

Venerable Macarius the Egyptian

The slave of glory cannot be the slave of God.

Hierarch John Chrysostom

Outward glory increases inward ignominy, and imaginary health, inspiring the thought in a man that he really is healthy, does not permit him to apply treatment.

Venerable Isidore of Pelusium
