Secondly, That Jesus Christ Himself, who came (into the world), was born of the Father before all creatures; that, after He had been the servant of the Father in the creation of all things— “For by Him were all things made” — He in the last times, divesting Himself (of His glory), became a man, and was incarnate although God, and while made a man remained the God which He was; that He assumed a body like to our own, differing in this respect only, that it was born of a virgin and of the Holy Spirit: that this Jesus Christ was truly born, and did truly suffer, and did not endure this death common (to man) in appearance only, but did truly die; that He did truly rise from the dead; and that after His resurrection He conversed with His disciples, and was taken up. (From the preface)

In De Principiis Origin seeks "to fix a definite limit and to lay down an unmistakable rule" on the essential nature of the trinity. His writings certainly excited debate, but he was widely recognized as a great scholar of scripture and hermeneutics. Origen died in 254.

Compare Origen's summary explanation of Jesus Christ with the following adopted in 325 by the First Council of Nicaea:

And in one Lord Jesus Christ, the Son of God, begotten of the Father the only-begotten; that is, of the essence of the Father, God of God, Light of Light, very God of very God, begotten, not made, being of one substance with the Father; By whom all things were made both in heaven and on earth; Who for us men, and for our salvation, came down and was incarnate and was made man; He suffered, and the third day he rose again, ascended into heaven; From thence he shall come to judge the quick and the dead.

In 381 the First Council of Constantinople amended the portions of the creed italicized. Other adjustments were made at later Councils.

The main themes can be readily recognized and are shared. The differences are subtle, but became - and have remained - sources of significant controversy. Origen clearly contributed to what we now understand as orthodox belief. But he is actually pre-orthodox or proto-orthodox.
