I’m not sure whether it was ever an “official designation”, but the middle chair behind the pulpit has always seemed to me to be appropriately styled to be a “bishop’s chair” and with the history of the pulpit (see answer to Q03) the name seems to fit. Actually, it was a gift from a “friend of the church”, John Sullivan, and nothing is known of any other historical significance. (Pat Singletary has an interesting story about how it was acquired, but I am never able to remember the details of it…she will have to write it down sometime.) Oh yes, if you try to move the chair, the top of it is likely to fall off, and if you pick it up, the casters fall out. (alas, these have been "fixed" since 2001.)
