OK, I read it at its source (the actual bulletin)...and this is the core of it:
Where possible, leaders should encourage couples to be both married and seal in the temple. Where a licensed marriage is not permitted in the temple, or when a temple marriage would cause parents or immediate family members to feel excluded, a civil ceremony followed by a temple sealing is authorized.
We anticipate that this will provide more opportunities for families to come together in love and unity during the special time of marriage and sealing of a man and a women.
So, the main reason appears to be family unity. But only family unity at the immediate level. If the single temple ceremony will cause disharmony among grandparents, or aunts and uncles, then the policy doesn't apply. I wish it said it was at the preference of the couple for reasons of harmony. Granted, nothing is stopping a couple from phrasing their concerns about parental or immediate familial discontent with a temple-only marriage in a way that justifies it, even when immediate family members are OK with either kind of wedding.
They do have a small reference to heterosexual marriage in bold above. I guess part of me doesn't trust the church as being forthright in its main reason -- to prevent it from having to formalize gay marriages. It would be too controversial to say that when they have a more benign reason. Whose consequences, I may add, they apparently knew all along but considered a worthy casualty.
So, I'm neutral on this one. The policy has both a positive and a negative message in it. I wish I had've joined the church a year from now, not 3 decades ago when all the hard stuff was treated as doctrine and fully justified by TBM's in the face of intense suffering on the part of people disadvantaged by policy/doctrine/culture. I hyphenate all of these as it's tough to know which is which these days. But let's let everyone save face in the name of progress.
