Christianity people get wrong impression from the sentences in inverted commas that the sentences within the inverted commas are words of Jesus. This is not the case:
"The double quotation mark is older than the single. It derives from a marginal notation used in
fifteenth-century manuscript annotations to indicate a passage of particular importance (not necessarily a quotation); the notation was placed in the outside margin of the page and was repeated alongside each line of the passage. By the middle
sixteenth century, printers (notably in
Basel,
Switzerland) had developed a typographic form of this notation, resembling the modern closing or right-hand double quotation mark. During the seventeenth century this treatment became specific to quoted material, and it grew common, especially in Britain, to print quotation marks (now in the modern opening and closing forms) at beginning and end of the quotation as well as in the margin; the French usage (see under
Specific language features below) is a survival of this. In most other languages, including English, the marginal marks dropped out of use in the last years of the eighteenth century."
