Forgive me... but I can't understand him for his heavy Brit accent.
Listen again. You might have better luck the second time. Father Morgan's speech is remarkably lucid; it is entirely free of crippling regionalisms in pronunciation and phrasing. A native speaker of English who is old enough to have heard the language spoken by educated people outside his immediate natal environment—that is, outside the circles of those with similar native woodnotes wild—ought to have no difficulty understanding him.
Instead, what difficulties there may be for some are traceable to the inevitably amateurish character of the recording, which is echo-ridden from start to finish—an all-too-common characteristic of cellphone videos. If the person who made the recording had used a small semi-pro recorder or had been able to run his original recording through a parametric equalizer at home before releasing it, 75 percent of the distorting echo might have been eliminated. Of course, circuмstances of off-the-cuff recordings, like the present one, seldom permit such amenities, unfortunately.
