I’m a Calvinist Protestant and a philosophically curious blogger; I interact with Roman Catholicism. Below are some quotes I find meaningful:

What altar of refuge can a man find for himself when he commits treason against the majesty of reason?

― Baruch Spinoza

Beware the man of a single book.

― Thomas Aquinas

We are what we repeatedly do. Excellence, then, is not an act, but a habit.

― Aristotle

2 Corinthians 10:3-5
New Revised Standard Version Updated Edition
3 Indeed, we live as humans[a] but do not wage war according to human standards,[b] 4 for the weapons of our warfare are not merely human,[c] but they have divine power to destroy strongholds. We destroy arguments 5 and every proud obstacle raised up against the knowledge of God, and we take every thought captive to obey Christ.

― The Apostle Paul
