Perhaps Ive been jaded by working on religion topics here but these seem far from blatant to me Its unsourced but it may well be perfectly accurate to say that the place is known for excellence in music and liturgy This is something that can be ascertained Recall this was  when footnoting was nowhere near as common as it is now and was not a necessary for an article to be considered wellcited and eligible for FA status See for example  from the time it was FAd on  May  Ditto for being at the center of community service Its not POV if its so considered in that community and they unquestionably keep themselves busy Id say these are POV if this is what the cathedral says about itself but not if its what others say about it In that case it ought to be sourced by current standards of course but thats a different problem
