A few years ago I had the privilege of re-writing (editing and authoring) the 14th edition of the venerable reference book The Handbook of Denominations in the United States published by Abingdon Press. One of the changes I made was to mention each denomination’s stated policy with regard to gay marriage and homosexual sexual relations. In some cases I could not find a stated, official policy, so I contacted the headquarters and spoke or corresponded with the highest leader possible.
Of the approximately 260 denominations listed and described in the volume, about 200 of them have official or unofficial policies against gay marriage and same-sex sexual relations. In some cases they asked me not to publish their policies, but they assured me they practice the policies even if they do not want it known outside their denominations.
They are worded very differently from each other; there is no “template,” so to speak. However, the vast majority of Christian denominations in the United States do not condone gay marriage among their ranks and do not approve of same-sex sexual relations. Many of them state that it is sin.
A few denominations take a kind of middle position–saying (for example) that they do not condone it among their own “people” but do not oppose it outside of their ranks. In other words, they are not going to fight or lobby to reverse the Supreme Court decision regarding equality of gay people with straight people in terms of government-recognized marriage. Most did not say anything about that. A few denominations take a middle position saying that they will include gay people–married and not married–within their membership ranks but will not perform gay marriages.
The overall impression, however, that I think is not well understood by most people, is that the vast majority of American Christian (and many non-Christian) church organizations, denominations, networks, independent congregations, do not approve of gay marriage or same-sex sexual relations.
It is not as if there are a “few hold outs;” the “hold outs” (in terms of denominations) are those relatively few who endorse and affirm gay marriage within their ranks.
A few so-called “mainline Protestant” denominations leave the issue up to regions (synods) or individual congregations. Some of those are now facing divisions over that. New denominations are forming all the time because of perceived permissiveness on this issue. The new denominations are almost all opposed to gay marriage.
An impression is circulating that only a few ultra-conservative, fundamentalist, hateful religious groups and institutions stand against gay marriage within their ranks, within their institutions, but that is a wrong impression.
Those Christian institutional leaders who feel under pressure to allow gay marriages within their ranks (student bodies, staff, etc.) need to know that they are not alone in holding the line against gay marriage within their ranks.
