Which makes me wonder how he felt about being put in the position of having to chose between the position his faith takes and that publicly espoused by his employer.
Without wishing to be provocative, did you ever wonder how Christian players felt about playing on Good Friday? Wasn't there a Scottish (I think) player who had it in his contract that he wouldn't be called upon to play on a Sunday?
I don't know about the Scottish player (although I do remember the Welsh manager of Cefn Druids, of all clubs, who wouldn't manage on a Sunday), but Symon Burgher of Bromsgrove Rovers in the nineties wouldn't play on a Saturday as he was a Seventh Day Adventist, and so played at a lower level than his ability merited.
Back in the day, although Sunday football was banned, there were regular games on Christmas Day (unless it was a Sunday) and Good Friday, both usually followed by a game the following day, so Christian players have not traditionally had a problem playing on those days.
