-The Confirmations will be happening at the newer church as far as I understand, not the historic chapel. A collection will be taken at the confirmations, I guess as a gift/rent for using the church.
-All Souls' has hosted the indult Mass in Orlando ever since the SSPX church opened.
-The bishop of Orlando is allowing this Mass at the church for ecuмenical reasons in light of Francis' recent gestures to the SSPX (e.g. Confession faculties, Marriage faculties, etc.). Cannon 137 was mentioned about this specifically by Bishop Noonan.
-Technically, the cemetery attached to All Souls also mentions when someone is buried authorized clergy are only to perform the Rites at the cemetery. SSPX clergy as far as I know always have been able to perform the Rites there where several lay people are buried that attended the SSPX Masses. I'm sure Cannon 137 would also be their explanation for this.
