Yeah those sources are massively retarded. The Roman Communion may believe all that crap, but it has nothing to do with the Holy Tradition. Orthodox Worship is every day of the week. Divine Liturgy is usually observed every Sunday, in honor of the Resurrection. But there’s no reason the Divine Liturgy can’t be observed any day or every day - but just once per day, per priest/parish. Usually that fullness happens in monastic communities. “Keeping the Sabbath” is not the same thing as “going to Church on Sunday”. Jesus Christ *is* the Sabbath. We Keep the Sabbath by being in Communion with His Church, observing the Signs and Seasons we received from the Holy Fathers, which includes, but is not limited to, the Holy Scriptures. The idea that we “only worship on Sunday instead of Saturday like we used to” is *patent nonsense*. The entire Festal Menaion has services every single day. In fact, today is a day we go in and worship, because it’s Theophany - the Baptism of the Lord. Notice; it’s not a Sunday, but rather a Tuesday. Might aa well bitch that we’re worshiping on a Tuesday. Because of these extremely basic, fundamental facts, the entire argument is completely irrelevant. We observe the Tradition we received from the Holy Fathers, who’ve been doing the same thing since the Apostles, who learned it from Jesus Christ Himself. We simply cannot be bothered with all this silliness. We know what we are doing.
