Roman emperors Honorius and Theodosius II issue a new law banning public gatherings and funerals for Anomeans (also known as Eunomians after one of their leaders, Eunomius of Cyzicus). Anomoeanism is an Arian sect which teaches that Jesus had a completely different nature from God. The label Anomoean comes from the Greek for "not similar".
The new Roman law states:
"We order that the nefarious assemblies and the funeral conventicles of the Eunomians shall be entire banned.
If any person usurp the title of bishops, clerics, or ministers and preside over Eunomian assemblies, or if any person allow Eunomian assemblies to be held in their homes or fields, they shall incur the sentence of proscription and all their goods confiscated.
Those persons discovered in their monstrous madness to rebaptize those imbued with orthodox faith, shall be punished." [CTh 16.6.7]
