Question: Some sources, like Wikipedia, claim there are no links between the Catholic Saint Valentine and Roman fertility practices such as the Lupercalia. Is Valentine's Day a holiday Christians should keep, based on this assertion?
Answer: When researching questions like this one, it is important to examine your sources carefully. For example, if you believe Wikipedia (as of late December 2012), Valentine's Day has no pre-Christian antecedents. However, a closer look at the various sources reveals a different answer.
