We recognize a tree by its fruit, and we ought to be able to recognize a Christian by his action. The fruit of faith should be evident in our lives, for being a Christian is more than making sound professions of faith. It should reveal itself in practical and visible ways. Indeed it is better to keep quiet about our beliefs, and live them out, than to talk eloquently about what we believe, but fail to live by it.

I would rather die and come to Jesus Christ than be king over the entire earth. Him I seek who died for us; Him I love who rose again because of us.

Where the bishop is present, there is the Catholic Church

Your accord and harmonious love is a hymn to Jesus Christ...in perfect harmony, and taking your pitch from God, you may sing in unison and in one voice to the Father through Jesus Christ.

For some are in the habit of carrying about the name in wicked guile, while they still practice things unworthy of God. You must flee these as you would wild beasts. For they are ravening dogs, who bite secretly, against whom you must be on your guard, since they are men who can scarcely be cured.

Wherever the bishop shall appear, let the multitude of also be, just as wherever Jesus Christ is, there is the catholic [i.e., universal] church. It is not lawful either to baptize or to celebrate a love feast without the bishop, but whatever he approves of, that is also pleasing to God.

But look at the men who have those perverted notions about the grace of Jesus Christ which has come down to us, and see how contrary to the mind of God they are. . . . They even abstain from the Eucharist and from the public prayers, because they will not admit that the Eucharist is the self-same body of our Savior Jesus Christ which flesh suffered for our sins, and which the Father of His goodness raised up again.
