Every Christian denomination traces back to Constantine and Augustine. From the Edict of Milan (AD 313) to today's 45,000+ denominations, this is the lineage of the man-made faith built atop Yeshua's name. Neither line on this page is the covenant remnant. For that, see the Ekklesia Timeline.
The Edict of Milan grants Christianity legal status under Constantine. Twelve years later, the Council of Nicaea fuses faith with empire. Pesach is replaced with Easter, the Sabbath shifts to Sunday by imperial edict, and Torah-keeping is recast as "Judaizing." The institutional church is born.
Augustine systematizes the doctrines that harden into Catholic orthodoxy: replacement theology, original sin, infant baptism, amillennial eschatology, predestination, and just-war theory. His shadow falls across every Western branch that follows. Without Augustine, no Catholic Church as we know it. Without him, no Calvinist or Lutheran framework either.

After the Schism, the Western church holds papal supremacy, the filioque, and centralized canon law. For 500 years it is the only institutional Christianity in Western Europe. Crusades, indulgences, monastic orders, scholastic theology, and the rise of the medieval papacy all flow through this single channel.

John Calvin
The Council of Trent codifies Catholic doctrine in response to Protestantism: tradition as co-equal with Scripture, transubstantiation, papal authority reaffirmed, and the Inquisition expanded. The Jesuit order (founded 1540) becomes the Church's intellectual and missionary arm. The Catholic Church does not return to Hebraic foundations; it doubles down on its Augustinian-Constantinian framework.

The First Vatican Council formally declares the Pope infallible when speaking ex cathedra on matters of faith and morals. The doctrine of papal infallibility, implicit in centuries of practice, becomes binding Catholic dogma. The institutional line solidifies its highest authority.
Azusa Street Revival, William J. Seymour
The Second Vatican Council modernizes Catholic practice: vernacular Mass, religious liberty affirmed, ecumenical openness toward Protestants and Eastern Orthodox, and revised relationships with non-Christian religions. Doctrine is reaffirmed in continuity with prior councils. The institutional line bends to modernity without renouncing its Augustinian foundation.
Cross-denominational
Calvary Chapel, Vineyard, Hillsong, Bethel
Roughly 2.4 billion people identify as Christian worldwide. According to the Center for the Study of Global Christianity, the global Christian movement has fragmented into more than 45,000 distinct denominations — Catholic, Orthodox, Lutheran, Reformed, Anglican, Baptist, Methodist, Pentecostal, Charismatic, Adventist, LDS, JW, non-denominational, and tens of thousands of regional and independent groups.
Every one of them started with a man. Every one of them carries Constantine's calendar and Augustine's theology somewhere in its DNA. None of them existed in AD 30. The fire reveals every man's work, gold or stubble.
