There is also a related meme purporting to quote Rep. Bachmann defending herself in making the original statement, also on Fox News - of course.
The source of this image is the Facebook group "Christians for Michele Bachmann". However, after looking through the posts made by the group it becomes very obvious, or perhaps not so obvious, that the group is about nothing more than satire - at worst they're deliberately trying to spread lies and misinformation. What I find more disturbing is that the image has been shared nearly 30,000 times directly (and who knows how many indirect shares, reposts etc.) and that people are using it as "evidence" of Rep. Bachmann's "stupidity" and the dangers of organized religion.
No matter where you stand on Rep. Bachmann or religion, I find it disgusting that people are using something with no verification to support & promote a certain position. Spreading lies, rumors, misinformation, etc. all leads to the further degradation of available information, entrenching division, hatred, and causes undue to harm to the reputation of very real human beings. If you think someone or something is stupid or wrong, use real evidence to back it up. There is no need to create lies. Doing so is beyond childish.
As for the statement itself, the phrase "if English was good enough for Jesus...." has actually been floating around the Internet for years and has been attributed to dozens of other people, each time with a different ending. The phrase itself however goes back even further. Miriam Ferguson (1875-1964) is alleged to have said, sometime in the 1920s, "if English was good enough for Jesus, it ought to be good enough for the children of Texas" speaking in reference to bilingual schools. Although variations of the phrase might actually go back to the 1880s and used derogatorily against Christians, and could make it very unlikely that Ferguson was actually the originator of the phrase.
I know people can't help themselves but to spread funny or shocking memes, especially if it re-enforces their own prejudices. But as a rule of thumb, if it sounds too idiotic or shocking - fact check it! Try to find a real news article, or a video showing the person actually saying it. If a politician, or anyone in the public light, truly said something completely insane you can be sure that the news media will pick it up and their detractors would run with it. So do us all a favor, take 30 bloody seconds and make sure what you're about to post is true.
