As a gifted speaker Eugene tried throughout his life to share his expertise with his Oblates so as to improve their presentation and consequently achieve the most benefit. The better the preaching of the Oblates, the more effective would be the results of their ministry. There are many examples of this in his writings, as this remonstration to Honorat illustrated:
The man who brought me your letter says that when you are in the pulpit, you put yourself in a mood of despair, that’s the word for it; but why utter such cries? If it is a natural failing which makes you shout all the time…. I have nothing to say except to deplore it but if you can do otherwise and yet shout, thinking you obtain better results thereby, you are greatly in error and quite at fault, for you are missing your aim and rendering yourself useless; in that case, it is a disorder. Get it firmly into your head that they lose half of what you say when you shout in that manner, and this is very annoying when it is an instruction that everybody should grasp. That is not the way to act, on the contrary, one should indulge somewhat rarely in outcries. That is the way to give them some effect.
Letter to Jean-Baptiste Honorat, 24 January 1824, O.W. VI n. 126
The preachers only had a limited time with their audience, and consequently they had to utilize that time to the fullest.
