Baha'u'llah's law does not consider semen unclean, Pork is allowed and the concept of "uncleanness" is abolished.

One of the major reforms in the Bahá’í teachings involves the laws of cleanliness, which were instituted in various faiths, including Hinduism and Judaism. In The Most Holy Book, Bahá’u’lláh revokes the notion of the uncleanness of various objects and people, specifically “of semen [and] of certain objects for purposes of prostration”. This serves as a perfect illustration of what I call a prescriptive religious reform.

In the Law of Moses, the discharge of semen was considered unclean: “If a man has an emission of semen, he shall bathe his whole body in water, and be unclean until the evening… If a man lies with a woman and has an emission of semen, both of them shall bathe in water, and be unclean until the evening” (Lev. 15.16, 18). Bahá’u’lláh’s law, in contrast, does not consider semen unclean despite the fact that in the last several thousand years the nature of semen obviously has not changed. As you can see, we are dealing not with natural but with ritualistic purity, which the Biblical text explicitly confirms: “when any man has a discharge from its member, his discharge makes him ceremonially unclean” (Lev. 15.2).

"The eating of pork is not forbidden in the Baha'i Teachings."

(From a letter written on behalf of Shoghi Effendi to an individual believer, March 27, 1938; quoted in Lights of Guidance, no. 1012)


“God hath, likewise, as a bounty from His presence, abolished the concept of "uncleanness", whereby divers things and peoples have been held to be impure. He, of a certainty, is the Ever-Forgiving, the Most Generous. Verily, all created things were immersed in the sea of purification when, on that first day of Ridvan, We shed upon the whole of creation the splendours of Our most excellent Names and Our most exalted Attributes.
