George Burton Adams,
The History of England from the Norman Conquest to the Death of John…
“ The excommunication was formally published in France, and news of it passed over to England, but no attention was paid to it there. For the individual, excommunication was a more dreaded penalty than the interdict. The interdict might compel a king to yield by the public fear and indignation which it would create, but an excommunication cut him off as a man completely from the Church and all its mercies, cast him out of the community of Christians, and involved in the same awful fate all who continued to support him, or, indeed, to associate with him in any way. ”
