Another sitting Episcopal bishop has announced he is heading Rome-ward. It is Bishop Steenson of the Diocese of Rio Grande, which appears to cover al of New Mexico and a bit of Texas.
His letter and a very interesting comments section at Stand Firm. The letter is a bit vague, but it has been confirmed that he is, indeed, coming into the Catholic Church. Do read the comments of William Tighe, in particular.

The reason for this decision is that my conscience is deeply troubled about where the Episcopal Church is heading, and this has become a crisis for me because of my ordination vow to uphold its doctrine, discipline, and worship. An effective leader cannot be so conflicted about the guiding principles of the Church he serves. It concerns me that this has affected my ability to lead this diocese with a clear and hopeful vision for its mission. I also have sensed how important it is for those of us in this position to model a gracious way to leave the Episcopal Church in a manner respectful of its laws.
I believe that God’s call to us is always positive, always a to and not a from. At the clergy conference next week I hope to be able to share something of this. Many of you already know of my love for the Catholic Church and my conviction that this is the true home of Anglicanism. I will not dwell on this, however, so as not to lose sight of my responsibility to help lay a good foundation for the transition that you must now lead.

Pray for him, his family, and pray that he receives a prayerful, joyous and supportive welcome in the Catholic Church.
(Which has not always been the case with previous similar examples,  but we can hope and pray that is changing…)
