I posted a lot of links, but maybe it would be more helpful to post the actual Q & A with relevant info bolded. The rest of the answer from Fr. Angel is worth reading too.
"Jeff:
Quote:
It is wrong to miss Mass without a grave reason.
It is wrong to fully and actively participate in a non-Catholic service.
It is not wrong to attend, in the interests of domestic tranquility, a non-Catholic service so long as we do not fully and actively participate (for example, taking communion) and it is known to those to whom it is relevant (such as our firiends and family) that we do not endorse the service as “just another church service equally valid with the Mass”.
That is my undersatnding.
**Jeff, I can cite papal encyclicals, especially “Mortalium Animos” of Pope Pius XI and the Vatican II Decree on Ecumenism. These documents forbid “comunicatio in sacris” which means participating together in worship. There is no distinction between “actively participate” and “passively participate.”
Do not get confused with the occasional participation in an ecumenical prayer service at which Catholic and Protestant clergy are present together. Those services are carefully planned out so that the faithful will not be exposed to anything which contradicts Catholic teaching.
Also, do not get confused with the occasional attendance at a wedding or funeral, which is done out of some urgent family need for attendance. Even these ceremonies would be off limits where there is the danger of scandal or exposure to dangers against the faith…** The case being discussed here is where one is routinely attending Protestant services and Catholic Mass has not been actively sought out first.
I don’t mind you disagreeing. But for the future, I ask that if you are going to enter a delicate pastoral question such as this, you need to research and back up your assertions with church documents. It gets very confusing when you take a contrary position and don’t cite anything more than “That is my understanding.”
“That is my understanding” sums up well why so many Catholics are Protestantized in their spirituality and approach to worship. The grave error of indifferentism, so vigorously condemned at Vatican I, and with pointed and scathing words against the US Catholic Church by Pope Leo XIII, is now mistaken to be the official Catholic position.
One does not know whether to laugh or cry at the lamentable state of affairs.
Sincerely in Christ,
Fr. Angel"
