You need to understand Church history better. We are currently working on reunification with the Eastern Rite Church. We already recognize their sacraments. This has nothing to with the first commandment.
Strange gods are those things that lead you away from God, Other division of the Christian faith that recognize the same God is not the same as false gods.
Deacon Frank
To make sure no one is confused by the terminology, we already have full communion with the “Eastern rite Churches,” AKA Eastern and Oriental
Catholic Churches. These churches use an Eastern rite like Byzantine, Coptic, Syriac, and so on AND they share full and unquestionable communion with Rome.
Most Eastern Catholic Churches were once Orthodox and they chose to leave the Orthodox communion and to join the Catholic communion. When they did that, they brought their hierarchy, theology, spirituality, liturgy, and so on with them so that the only thing that changed was who they intercommuned with. These people are fully Catholic and are in the same communion as the Pope of Rome.
We’re working and praying for full communion with the Eastern and Oriental
Orthodox as well. Catholics recognize the fullness of truth and the validity of the sacraments in the Orthodox Churches, saying the only thing lacking is Christian unity. Some modern converts and Orthodox theologians say that Orthodoxy’s teachings are different from Rome’s teachings on important points, but Rome rejects those understandings of Orthodoxy and believes that a true and honest look at Orthodox theology shows that it is not inconsistent with Roman theology.
There are some legitimate points of concern and discussion between the Orthodox Churches and Rome, most of which revolve around the topic of jurisdiction and church governance.
Eastern Catholic = Catholic. In full communion with Rome.
Eastern Orthodox = Orthodox. Don’t share communion with Rome.
Both the Eastern Catholics (or Eastern rites as they’re sometimes called) and the Eastern Orthodox use the Byzantine cross. Both the Oriental Catholics and the Oriental Orthodox use the Coptic, Syrian, etc crosses.
The cross being discussed isn’t Orthodox, it is Byzantine.
Byzantine is also Catholic.
It’s fine for Catholics to be nourished by the traditions of the East, which are preserved by both the Eastern Catholic and the Eastern Orthodox Churches.
Since, in fact, we believe that the venerable and ancient tradition of the Eastern Churches is an integral part of the heritage of Christ’s Church, the first need for Catholics is to be familiar with that tradition, so as to be nourished by it and to encourage the process of unity in the best way possible for each.
Our Eastern Catholic brothers and sisters are very conscious of being the living bearers of this tradition, together with our Orthodox brothers and sisters. The members of the Catholic Church of the Latin tradition must also be fully acquainted with this treasure and thus feel, with the Pope, a passionate longing that the full manifestation of the Church’s catholicity be restored to the Church and to the world, expressed not by a single tradition, and still less by one community in opposition to the other; and that we too may be granted a full taste of the divinely revealed and undivided heritage of the universal Church which is preserved and grows in the life of the Churches of the East as in those of the West.
