what does this mean?

“They say the poor man is haunted by the fear that he will die during a general election, and that his obituary notices will be seriously curtailed by the space taken up by the election results. The curse of our party system, from his point of view, is that it takes up so much room in the press.”
The Archdeacon smiled indulgently. As a man he was so exquisitely worldly that he fully merited the name of the Heavenly Worldling bestowed on him by an admiring duchess, and withal his texture was shot with a pattern of such genuine saintliness that one felt that whoever else might hold the keys of Paradise he, at least, possessed a private latchkey to that abode.
“Is it not significant of the altered grouping of things,” he observed, “that the Church, as represented by me, sympathises with the message of Sherard Blaw, while neither the man nor his message find acceptance with unbelievers like you, Lady Caroline.”

I don't quite understand what the Archdeacon means here. Could someone please explain it to me? Thanks
