Perseverance

The tree is made manifest by its fruit; so those that profess themselves to be Christian shall be recognized by their conduct. For there is not now a demand for mere profession, but that a man be found continuing in the power of faith to the end. - St. Ignatius of Antioch's Letter to the Ephesians

Eucharist

...breaking one and the same bread, which is the medicine of immortality, and the antidote to prevent us from dying. - St. Ignatius of Antioch's Letter to the Ephesians

Courage

Let fire and the cross; let the crowds of wild beasts; let tearings, breakings, and dislocations of bones; let cutting off of members; let shatterings of the whole body; and let all the dreadful torments of the devil come upon me; only let me attain to Jesus Christ. - St. Ignatius of Antioch's Letter to the Romans
