What is the Byzantine-Ruthenian Catholic Church?.
It's from the The Eparchy of Passaic so has a Catholic outlook but it's a good primer of how we came to be.
Here's two picture sets of Ruthenian Parishes.
My cradle parish: Sts Peter and Paul BCC, Beaver Meadows, PA
and my Grandmothers parish: St. Mary's (Dormition) Byzantine Catholic Church, Hazleton, PA,
I attended Divine Liturgy at both regularly.
