Was the early church father Irenaeus (died 190) a Trinitarian?

This is the fifth article in the series that discusses the Christology of the main Christian authors of the first three centuries after Christ.  The previous articles were an Introduction, which defined the Trinity doctrine and gave an overview of the conceptual and historical development of it.  This was followed by articles discussing the views of Polycarp, Justin Martyr and Ignatius of Antioch.  This fifth article discusses the view of Irenaeus, bishop of Lyons (115-190).  He wrote as follows:

The Church … has received … this faith … (in)
One God, the Father Almighty, Maker of heaven, and earth, and the sea, and all things that are in them; and in
One Christ Jesus, the Son of God, who became incarnate for our salvation; and in
the Holy Spirit

To Christ Jesus, our Lord, and God, and Savior, and King, according to the will of the invisible Father, ‘every knee should bow, of things in heaven, and things in earth, and things under the earth, and that every tongue should confess; to him, and that He should execute just judgment towards all … (Against Heresies X.l)


Irenaeus identified the Father as the “Almighty,” in contrast to Jesus Christ.  That implies that the Son is not the Almighty. 

He believed that the Father is “the only and the true God.”  But he also referred to Christ Jesus as “our God.”  This is discussed in the article, Jesus is our god.  In summary, to capitalize the “G” of “god” is a translation that assumes and applies the Trinity doctrine and must not be used to support the Trinity doctrine.

Both the God of the Old Testament and Jesus are called “Lord.” This is also not proof that Jesus is God.  Firstly, the “one God” statements make a clear distinction between the “one God” (the Father) and the “one Lord, Jesus Christ.”  Secondly, the Greek word translated “lord” has a wide range of meanings.  It can simply be a respectful form of address to somebody in a more senior position but gods were also addressed as “lord.”

Every knee should bow” before Christ Jesus because that is “the will of the invisible Father;” not because Jesus is the Almighty.  That Jesus is worshiped because it is the Father’s will implies that the Son is subordinate to the Father.  Irenaeus explicitly refers to the Father as “the Head of Christ.”

These concepts will now be discussed in more detail.


Irenaeus identified the Father as the “Almighty,” in contrast to Jesus Christ.  That implies that the Son is not the Almighty.  It is also not possible for two Almighty beings to exist, for then one would limit the might of the other.
