Certainly an anachronism in 1991! Pre- Stonewall gay-rghts movements in the United States, led by organizations like the Mattachine Society, sometimes called themselves "homophile" movements. They were attempting to replace the more clinical "homosexual" with "homophile."

In the late 1960s, the Mattachine Society branch in Los Angeles helped provide the data that led to the removal of homosexuality as a disorder in the DSM, the official mental-health diagnostics manual.

The history of this struggle is largely what led U.S. queer folks to definitively reject "homosexual" as an identity label.

But long before 1991, it was clear we had rejected "homophile" just as firmly, and for pretty much the same reason — the "phile" suffix association with mental-health disorders and pathological behavior.

And of course, by 1970's first Pride marches, "gay" became almost universally accepted among queer people as a label. Until about 1990, it was much more of an umbrella term than it is today, similar (but not the same!) to how "queer" operates now.

It's odd that by that late date, the Church would have attempted to resurrect a term that some activists had used for a while but that was later rejected as insulting. A bit tone deaf! Somebody was apparently not doing much listening.
