I've got one more question. I presume that the Byzantine Rite has some kind of an una cuм in its formulary. Is that correct?
I ask because there's a monthly UCGG Mass in my area, at a novus ordo church. I'm wondering if I could go there for an extra Mass per month.
It seems an Eastern Rite una cuм is less odious than an SSPX una cuм. But maybe I'm just being extremely dishonest.
