epistle/apostle

When I listened again to the Litany of Saints posted yesterday, without warning I noticed the similarity of epistle and apostle from the sound of the two words and their spellings. Epistle means “letter”, and apostle means “one sent”. We send a letter.

Epistle etymology: from Latin epistola “a letter,” from Greek epistole “message, letter, command, commission,” whether verbal or in writing.

Apostle etymology: from Late Latin apostolus, from Greek apostolos “messenger, envoy,” literally “person sent forth.” Compare epistle.

I also use the Catholic Encyclopedia for a variety of topics because it has been referenced by popes, which makes it credible.

Frequent returns to blog posts undo errors and straighten meanderings unedited by anyone other than myself. Send your comments. I use many resources, such as
