The primary causes of the Schism were disputes over papal authority—the Pope claimed he held authority over the four Eastern Greek-speaking patriarchs, and over the insertion of the filioque clause into the Nicene Creed.

The resulting split divided the European Christian church into two major branches: the Western Roman Catholic Church and the Eastern Orthodox Church. This split is known as the Great Schism, or sometimes the “East-West Schism” or the “Schism of 1054.”

The Great Schism of 1054 was the breakup of the Christian church into two sections—the Western and the Eastern sections. The major effect of the Great Schism was that it created two separate churches: the Eastern Orthodox Church which was located in Constantinople and the Western Catholic Church.

The Great Schism of 1054 was when the Christian Church split into the Roman Catholic and the Eastern Orthodox Churches due to disputes on who had the most power within the church and whether icons could be used or not. The patriarch, also known as the leading bishop, and other bishops headed the church as a group.

The schism in the Western Roman Church resulted from the return of the papacy to Rome under Gregory XI on January 17, 1377, ending the Avignon Papacy, which had developed a reputation for corruption that estranged major parts of western Christendom.

The Three causes of the Great Schism in Christianity are:

• Dispute over the use of images in the church.
• The addition of the Latin word Filioque to the Nicene Creed.
• Dispute about who is the leader or head of the church.

The Catholic Church believes the pope to be infallible in matters of doctrine. Orthodox believers reject the infallibility of the pope and consider their own patriarchs, too, as human and thus subject to error. Most Orthodox Churches have both ordained married priests and celibate monastics, so celibacy is an option.

So, why does the Filioque matter? The answer is simply that it matters because the ontological nature of the Trinity determines how God accomplished our salvation. The Spirit must proceed from both the Father and Son to make the economic Trinity consistent.

New Testament Revelation 22:1 states that the river of the Water of Life in Heaven is “flowing from the throne of God and of the Lamb” (the Lamb is Christ, cf. John 1:29), which may be interpreted as the Holy Spirit proceeding from both the Father and the Son.

By confessing the Spirit as he “who proceeds from the Father”, it affirms that he comes from the Father through the Son. The Western tradition expresses first the consubstantial communion between Father and Son, by saying that the Spirit proceeds from the Father and the Son (Filioque). …

In mainstream trinitarian Christianity, God the Father is regarded as the first person of the Trinity, followed by the second person, God the Son (Jesus Christ), and the third person, God the Holy Spirit.

We believe in the Holy Spirit, the Lord, the giver of life, who proceeds from the Father and the Son, who with the Father and the Son is worshipped and glorified, who has spoken through the prophets. We believe in one holy catholic and apostolic Church.

The earliest creed in Christianity, “Jesus is Lord”, originated in the writings of Saint Paul. One of the most widely used Christian creeds is the Nicene Creed, first formulated in AD 325 at the First Council of Nicaea.

Nicene Creed, also called Niceno-Constantinopolitan Creed, a Christian statement of faith that is the only ecumenical creed because it is accepted as authoritative by the Roman Catholic, Eastern Orthodox, Anglican, and major Protestant churches. …

Ecumenical creeds is an umbrella term used in Lutheran tradition to refer to three creeds: the Nicene Creed, the Apostles’ Creed and the Athanasian Creed.

Apostles’ Creed, also called Apostolicum, a statement of faith used in the Roman Catholic, Anglican, and many Protestant churches. It is not officially recognized in the Eastern Orthodox churches. An example of such interrogations used in Rome about 200 has been preserved in the Apostolic Tradition of Hippolytus.

The Apostle’s Creed I believe in the Holy Spirit, the holy Catholic Church, the communion of saints, the forgiveness of sins, the resurrection of the body, and the life everlasting.

On Sundays and solemnities, one of these two creeds is recited in the Roman Rite Mass after the homily. In the Byzantine Rite, the Nicene Creed is sung or recited at the Divine Liturgy, immediately preceding the Anaphora (Eucharistic Prayer), and is also recited daily at compline.

The creed itself uses the language of public worship by speaking of the worship of God rather than the language of belief (“Now this is the catholic faith: We worship one God”). In the mediaeval Catholic Church, the creed was recited following the Sunday sermon or at the Sunday Office of Prime.

The eucharistic prayer follows, in which the holiness of God is honoured, his servants are acknowledged, the Last Supper is recalled, and the bread and wine are consecrated.

Ecce Agnus Dei Before receiving Communion himself and before distributing Communion to others, the priest “shows the faithful the Eucharistic Bread, holding it over the paten or over the chalice, and invites them to the banquet of Christ”. In doing so, he says: Ecce Agnus Dei, ecce qui tollit peccata mundi.

Church teaching places the origin of the Eucharist in the Last Supper of Jesus with his disciples, at which he is believed to have taken bread and given it to his disciples, telling them to eat of it, because it was his body, and to have taken a cup and given it to his disciples, telling them to drink of it because it …

The Mass is split into four main parts: Introductory Rites – includes the Opening Prayer, Penitential Rite and the Gloria. Liturgy of the Word – includes the Readings, Gospel, Homily and Prayers of the Faithful. Liturgy of the Eucharist – includes the Eucharist Prayer, the Our Father and Holy Communion.

The mass consists of two principal rites: the liturgy of the Word and the liturgy of the Eucharist. The first includes readings from Scripture, the homily (sermon), and intercessory prayer.
