I don't know Metropolitan Jonah but Subdeacon David said a few things that merit a comment.
First, Metropolitan Jonah was NOT the first or only Orthodox hierarch to be a part of the Right to Life rallies or movements. His predecessor, Metropolitan Herman, first as Bishop and then as Metropolitan established the Orthodox presence at the Washington rallies starting in the mid-1980's. Together with the late Metropolitan Nicholas of ACROD, the two of them were regular participants bringing with them busloads of the faithful each January. Metropolitan Nicholas was there through 2009 when his declining health precluded his participation.
In ACROD, our two most recent hierarchs, the late Bishop John (Martin) and Metropolitan Nicholas have preached about, written annual pastoral messages and steadfastly reminded their flock regarding the Church's position on homosexuality and abortion. Some of you out there act as if this position is new or somehow we Orthodox didn't 'get' it until Metropolitan Jonah appeared on the scene several years ago.
On both our website and in our annual publications, teaching material has been posted and updated going back to my college days in the 1970's on these issues. They are summarized and linked here. http://www.acrod.org/readingroom/ethics
As to the calendar, to many of us it is a non-issue - one way or the other.
Finally, for many of us not within the OCA, we have been concerned about Metropolitan Jonah since his ill-tempered remarks in Texas given at the start of Great Lent shortly after his election as Metropolitan. While he has taken steps to distance himself from the harshest aspects of that address it is an old saying that deeds speak larger than words and only time will tell.
