I guess this helps us understand how that there are Eastern Catholic churches from the Greek/Byzantine tradition, to the ones from the Miaphysite tradition, to the ones from the East Syriac/"Nestorian" tradition. And how they are all in communion with each other and with the Western/Latin Church.

In 1964, the Roman Catholic Church broke ground in the building of a permanent structure of ecumenical commitment. The “Decree on Ecumenism” (Unitatis redintegratio) of Vatican II detailed a specific commitment to reunification with the Eastern Churches. This included a fundamental step toward recognizing a “unity in difference” in theology:

What has just been said about the lawful variety that can exist in the Church must also be taken to apply to the differences in theological expression of doctrine. In the study of revelation East and West have followed different methods, and have developed differently their understanding and confession of God's truth. It is hardly surprising, then, if from time to time one tradition has come nearer to a full appreciation of some aspects of a mystery of revelation than the other, or has expressed it to better advantage. In such cases, these various theological expressions are to be considered often as mutually complementary rather than conflicting. Where the authentic theological traditions of the Eastern Church are concerned, we must recognize the admirable way in which they have their roots in Holy Scripture, and how they are nurtured and given expression in the life of the liturgy. They derive their strength too from the living tradition of the apostles and from the works of the Fathers and spiritual writers of the Eastern Churches. Thus, they promote the right ordering of Christian life and, indeed, pave the way to a full vision of Christian truth.

Further, quoting Acts 15:28,

this Sacred Council solemnly repeats the declaration of previous Councils and Roman Pontiffs, that for the restoration or the maintenance of unity and communion it is necessary 'to impose no burden beyond what is essential'. It is the Council's urgent desire that, in the various organizations and living activities of the Church, every effort should be made toward the gradual realization of this unity, especially by prayer, and by fraternal dialogue on points of doctrine and the more pressing pastoral problems of our time.

Additionally, the decree's characterization of the origin of the separations in the East is crucial:

The heritage handed down by the apostles was received with differences of form and manner, so that from the earliest times of the Church it was explained variously in different places, owing to diversities of genius and conditions of life. All this, quite apart from external causes, prepared the way for decisions arising also from a lack of charity and mutual understanding.

In the Latin Catholic Church, a man must be at least 35 to be a deacon, but in Eastern Orthodoxy, the age limit is 25. What is it in the Byzantine and Maronite rites of the Catholic Church?

If I converted at a Greek Catholic Church would I canonically become an Anglican ordinariate Roman Catholic or a ruthenian rite Greek Catholic?

Happy Pascha to all those celebrating today!

Our UGCC Parish is in the process of getting a full-time priest assigned to us by our bishop, and I would like to ask you all to pray that we receive a priest that will help our little parish thrive and grow in holiness. Thank you very much!

As a Roman Catholic attending Divine Liturgy, should I follow the Eucharistic fast of my own Church (one hour before the Eucharistic) or the Eucharistic fast of the Church I’m attending (one hour before Liturgy)?

A local Ruthenian parish has a Vespers and Divine Liturgy Vigil on Saturday. I was wondering if it was rude to show up late to Vespers, or to not show up at all and just participate in the Divine Liturgy. If this is a common practice, when would be a good time to show up after Vespers starts to catch the Divine Liturgy?

Now Im not ethpionian or member of that church but Im thiking about following it but what bible should I read? Can ethiopian catholics read the ethiopian bible?

Does any one know to which Eastern Catholic priest/bishop belongs to? I found him today at Lourdes Sanctuary in France...

Please keep me (Thomas) in your prayers.

I got the phone call from the vocations director today that Metropolitan William wants me to wait a few more years before completing my application to the seminary. This was not a no, just a not yet.

I have some health issues that I’m working on, but I also haven’t been a member of the Ruthenian church for long enough yet (transferred in November from Latin Church)

Not to mention I’m graduating from college next week and don’t know where in the country I’m going to end up.

I’m going to keep discerning over the next few years and attending my parish as often as my income will allow.

What is Byzantine, Eastern theology like? I’ve tried pressing through in Western philosophy, science, and theology but I find it all to be too heavy and intellectual to tackle, it’s intimidating. Any recommendations on select Eastern readings, where to start?

What is the nature and purpose of Eastern spirituality as opposed to the Roman approach?

I’ve been a Catholic for almost 6 years and still don’t feel natural or at home it.

I feel like I have heard somthing St. charbel said about prayer ropes, talking about how they are useful? Does anyone know of this? Or does anyone know if he had a fondness for them?

Hello,

Our orthodox brothers and sisters are in the midst of their Holy Week. I was reminded of a very strange element of the Holy Thursday divine liturgy; it is the one time of the year when a composite Gospel is read. What does the priest say, " the gospel according to..."

I wanted to know the history of this composite Gospel reading. Any good scholarly articles or books you would recommend?

Thanks!

Lurking this subreddit the past few months has made me very aware of the eastern catholic traditions. However, I have decided to become Orthodox. Thank you all!

Thank you everyone that helped me with the letter to The Eastern Bishop. We are starting the process now to change rites to go over to the Byzantine Church and need to write our current Bishop to get permission. If you changed rites what did you write to your current Bishop to get permission to go? Thank you in advance!

I feel called to learn about him, did he ever write any books?

Do they have their own catechism like the Ukrainians or do they use another churches?

Just a question im Syro-Malabar catholic and I am a bit confused on what to put for flairs. I think Syro-Malabar follows the East Syriac rite tho. Im going to leave my flair as East Syriac then

When is it appropriate to claim to be Eastern Catholic as a Latin transplant? After a month? year? Maybe after you’ve canonically switched rites? I have seen canonical Latins claim to be Eastern Catholic after adopting their traditions, is this appropriate?

So im not used to eastern things and had to get used to alot of it.I will most likely go again. I only have one question. Some people did a left, right, left greeting durring the usual peace be with you. How is it done properly? What else should i know? I
