Eusebius claimed that orthodoxy derived directly from the teachings of Jesus and his earliest followers, and had always been the majority view; by contrast, all other Christian views were branded as "heresies", that is to say, willful corruptions of the truth, held by small numbers of minorities.

in the beginning of the second century. Imperial authorities arrested him "evidently for Christian activities" and condemned him as fodder for wild beasts.
He expressed eagerness to die, expecting thus to "attain to God". Following Ignatius, many proto-orthodox theorists saw it as a privilege to die for faith. In fact, martyrdom became a way to tell the true believers from the heretics. Those who were not willing to die for what they believed were seen as not dedicated to the faith.
Another facet of the faith was the structure of the church. It was common, as it is today, for a church to have a

He exhorted church members to listen to the bishops since they were the leaders: "Be subject to the Bishop as to the commandment…We are clearly obligated to look upon the bishop as the Lord himself ... You should do nothing apart from the bishop." The role of the bishop paved the way for hierarchies in churches that is often seen today.
Another important aspect about proto-orthodox Christianity involves its views on Jews and Jewish practices. An important book for them was the

Criticism
The traditional Christian view is that orthodoxy emerged to codify and defend the traditions inherited from the
Apostles

themselves. Hurtado argues that Ehrman's "proto-orthodox" Christianity was rooted into
first-century Christianity:
...to a remarkable extent early-second-century protoorthodox devotion to Jesus represents a concern to preserve, respect, promote, and develop what were by then becoming traditional expressions of belief and reverence, and that had originated in earlier years of the Christian movement. That is, proto-orthodox faith tended to affirm and develop devotional and confessional tradition ..Arland Hultgren[''The rise of normative Christianity'', Minneapolis: Fortress Press, 1994.] has shown that the roots of this appreciation of traditions of faith actually go back deeply and widely into first-century Christianity.

argues that the "proto-orthodox" category tends to obscure what he says are the diversity of views among the very Christian thinkers and groups that are categorized as "proto-orthodox," sustaining an erroneous backward-looking view that a unified "proto-orthodox" viewpoint had existed from the early days of Christianity when no such unified group existed even in contrast with Ebionites, Marcionites, and Valentinian Christians:

Christian — and, for that matter, Jewish — self-differentiation in this period was always a multilateral affair and resulted in diverse forms of Christian thought and practice. The inclusion of these varied modes of Christian piety in the single category of 'orthodoxy' was in fact the achievement of the post-
Constantinian imperial church and even then was never full or complete, but always partial and contested."
