I often wonder if things like this are a deliberate attempt by our separated brethren to openly shame The Church and stir up anti catholic sentiment. If a non catholic church (location) which is well known but often is confused with a catholic cathedral host a service like this one, two things are accomplished:
Makes anti catholics dislike the church more out of confusion.
Makes protestants feel that their churches are more tolerant and charitable than the catholic church.
Either way this was allowed in an effort to cause confusion, and to strip away the necessary distinctions between christian and non christian denominations.
As a side note I was almost denied a grade in a sociology class because I refused to attend a prayer service at a mosque down the street from my former college. This mosque was not hosting a christian service so I declined and did another assignment in its place. What disturbed me is how we are always being encouraged to host Muslim prayer services in the parishes here in sacramento but no mosque would ever host an advent service but want us to host Ramadan services. They excuse used is that though christians believe in the same god, we are considered/accused of being poly-thiest therefore a service honoring “many gods” could never be permitted. But since we have God in common we are expected to be open to services that don’t recognize who Jesus actually is.
I think in time there will be such a muddling of beliefs that no distinctions will be tolerated. Everything will be scrubbed and a basic spirituality will be all that’s allowed for christians with god or whatever you choose being what is worshiped including ones self in time eventually getting down to a totally atheistic society as a whole. It can and will happen if we do nothing.
