Some of you have been asking me which one of the acronyms behind my name is the correct one, SFO or OFS, since you've observed that I'd been using SFO for years and have now abruptly switched to OFS.
I'm a professed member of the Secular Franciscan Order whose original name in the Latin is Ordo Franciscanus Sæcularis. Since 1978, members of the English-speaking world had been using the acronym SFO behind their names to indicate that they were professed members of the Order. This was deemed appropriate, since the acronym reflected the correct sequence of the Order's name in English.
A new instruction has been issued in the past couple of months. As some of you are aware, the Secular Franciscan Order holds its Chapter at the International level every three years (every other time, or every six years, is an Elective Chapter). At the General Chapter of the Secular Franciscan Order in October 2011, it was decided that the acronym to be used when signing one's name is to be OFS and no longer SFO. The change was adopted in order to provide worldwide uniformity, as we are an international order.
Below is the official statement from the General Minister of the OFS...
ORDO FRANCISCANUS SÆCULARIS
