Salmos 9

Salmos 9:14

We need to direct our whole intention, dearly beloved brothers, to learning the mysteries of the faith, and we need to show that our works accord with our faith. With all vigilance we need to beware of the multifarious and subtle snares of the gates of hell, so that, in accordance with the word of the psalmist, we may be worthy to be snatched from these [snares] by the Lord's aid and to announce his praises at the gates of the daughter of Zion, that is, to enter into the joys of the heavenly city. And we should not think that it is sufficient for our salvation if either in our faith or our acts we [merely] come up to the level of the undiscerning and untaught crowd, for whom there is prescribed in the sacred literature only one rule of believing and of living. But as often as the examples of those who have gone astray are made known to us, let us immediately turn away the eyes of our mind so that they may not see vanity, and instead with attentive heart let us examine what truth itself discerns, following the example of blessed Peter. He rejected the false ideas of those who were in error, and with unhesitating words he delivered his confession of the hidden mystery of the faith he had come to recognize, and he kept [it] with unconquerable care in his heart. — Homilies on the Gospels 1:20
