 In the early 3rd century, Hippolytus of Rome wrote a treatise "Against Noetus", in response to a Christian from Smyrna named Noetus who had been promoting Patripassian views, which Hippolytus deemed heretical.Noetus and other Patripassians, such as Praxeas (see above, in relation to Tertullian), claimed that the Father as well as the Son had suffered on the cross.Like Tertullian, Hippolytus explicitly used the word Trinity in his treatise against Patripassian views
