Wow, more than half (granted only out of 10) so far are no tattoos. I thought I’d be one of the only ones. Among my friends, most of them have tattoos, but I don’t have a lot of Catholic friends yet (some of my Catholic friends have them though.) I’ve never had one, and never intend to have one.
Since this is in philosophy, I should comment on the ethics of tattoos: There is nothing intrinsically wrong with tattoos, unless they are for pagan ritual reasons; such as a runic inscription as a spell or “bind rune.” I used to study the FUTHARK runes, and know about such uses. I’ve had a few friends who had such “bind rune” tattoos, intended as “spells,” but of course they were all pagans (when I was pagan.) So, as long as it’s just a decoration, or a dedication to a saint or something safe like that, I see no problem with it.
The prohibition in the Bible was specifically telling them not to copy a specific culture’s tattoo traditions, and since it was the only tattoo tradition they knew, it became no tattoos at all. Modern Orthodox Jews (and some other Jewish believers) still hold to the “no tattoos,” and I’ve heard having them makes you ineligible to be buried in a Jewish cemetery; however, as Christians we usually don’t believe that rule applies anymore. Some Christian groups would disagree, and also speak against piercings and non-kosher eating, but that’s not the Catholic Church.
