The three main branches of Christianity

I know my book and website/blog are heavily weighted as Catholic (I think) in nature, but in actuality, my intention is not to convert people to my point of reference, the Catholic Church and its Magisterial Teachings.

It is my opinion that our main duty as Christians is not to convert but to bear witness to Christ, through our actions in serving others, through the sacrificial care and love for those less fortunate.

I am simply expressing what God has called me to in this lifetime.

I grew up Eastern Orthodox as a child and young adult and was given a solid grounding in Christianity and a Sacramental way of life.

I had a profound, private, spiritual awakening in college to Christ's sacrificial love through the heroic witness of a disabled fellow Orthodox friend.

I converted to Catholicism shortly after because it taught me, through the witness of the Saints and the Magisterium, how to live an authentic Christian life (not easy).

And finally, when I once found myself homeless for a short period of time, no one would lift a finger to help me except a good Protestant friend and then the local Protestant Christ Rescue Mission for a couple of months while I gathered myself back on my feet. 

(By the way, I was blown away by some of the expository Bible studies that some of the ministers there presented in the chapel.)

In no way was I tempted to abandon my Catholic Faith.

I learned over the years a profound lesson in respect. 

The respect that God has for us and the respect we should have for each other's boundaries.

I re-present here a Google search regarding what the three main branches of Christianity are:

Christianity is traditionally divided into three main branches: Roman Catholicism, Eastern Orthodoxy, and Protestantism. These streams emerged from major historical events, primarily the East-West Schism (1054 AD) and the Protestant Reformation (16th century). [1, 2, 3]

These branches share core beliefs in the Trinity and the life, death, and resurrection of Jesus Christ, but differ in governance, tradition, and theology: [1, 2]

1. Roman Catholicism

• Authority: The Pope in Rome, who is the visible head of the church.
• Beliefs: Authority rests equally in Scripture and church tradition. Salvation comes through faith and the Church's seven sacraments.
• Leadership: Highly centralized and hierarchical. [1, 2]

2. Eastern Orthodoxy

• Authority: Decentralized; led by a group of autocephalous (independent) bishops (Patriarchs).
• Beliefs: Focus heavily on church tradition, the writings of the Church Fathers, and the decisions of the seven ecumenical councils.
• Structure: Autonomous national churches (e.g., Greek, Russian, Antiochian Orthodox) that are unified in doctrine and liturgy. [1, 2, 3, 4, 5]

3. Protestantism

• Authority: Sola Scriptura—the Bible is the only infallible source of authority for Christian faith and practice. [1, 2]
• Beliefs: Salvation is by grace alone through faith alone. Most Protestants observe two sacraments: Baptism and the Eucharist (Communion). [1, 2, 3]
• Leadership: Highly decentralized, resulting in a wide array of denominations (e.g., Baptist, Methodist, Lutheran, Presbyterian, and Pentecostal).
