Noetus (Greek: Νοητός) was a presbyter of the church of Asia Minor about AD 230.
He was a native of Smyrna, where (or perhaps in Ephesus) he became a prominent representative of the particular type of Christology now called modalistic monarchianism or patripassianism.
[1] His views, which led to his excommunication by local presbyters, are known chiefly through the writings of Hippolytus, his contemporary at Rome, where he settled and had a large following.
He accepted the fourth Gospel, but regarded its statements about the Logos as allegorical.
The Catholic Encyclopedia notes: "It is true that it is easy to suppose Tertullian and Hippolytus to have misrepresented the opinions of their opponents".
