Patrick discusses how careful he was to protect his reputation so that it would reflect well on Christ.  He did not want anyone to be able say he took money or other benefits based on his position.

They were talking among themselves behind my back, and saying: “Why is this fellow throwing himself into danger among enemies who know not God?” Not from malice, but having no liking for it; likewise, as I myself can testify, they perceived my rusticity. And I was not quick to recognize the grace that was then in me;

I now know that I should have done so earlier.

Now I have put it frankly to my brethren and co-workers, who have believed me because of what I have foretold and still foretell to strengthen and reinforce your faith. I wish only that you, too, would make greater and better efforts. This will be my pride, for “a wise son makes a proud father [Proverbs 10:1; 15:20].

What is more, when I baptized so many thousands of people, did I hope for even half a jot from any of them? Tell me, and I will give it back to you. And when the Lord ordained clergy everywhere by my humble means, and I freely conferred office on them, if I asked any of them anywhere even for the price of one shoe, say so to my face and I will give it back
