"Abomination" is an approximation of the Hebrew "To'aiva". In fact homosexual relations are twice called a To’aiva.

Usually the Rabbis do not explain the meaning of Torah words. And the meaning of abomination seems reasonably clear - it is abhorrent to God. But in this case, the Talmud does offer a specific explanation. Based on a play on the Hebrew words, the Talmud says that in the act of homosexuality, the person is straying.

The commentaries on the Talmud say that by abandoning heterosexual sexual relations, the person is straying from one of his prime goals in life - to procreate and populate the earth. Although the rabbis did not use the term "natural law", this is precisely what they are describing.

In fact orthodox Judaism and Catholicism see the matter identically.

Attempting to gloss this with supposed reference to the Canaanites to feign some sort of moral basis for the acceptability homosexual behavior is totally Western and 20th century phenomenon. Period.
