"“Roman citizens who suffer that they themselves or their slaves be circumcised in accordance with the Jewish custom, are exiled perpetually to an island and their property confiscated; the doctors suffer capital punishment. If Jews shall circumcise purchased slaves of another nation, they shall be banished or suffer capital punishment.” St Justinian (The original law came from Julius Paulus)
"the circumcision in which they trusted is abolished. For He declared that circumcision was not of the flesh, but they transgressed because an evil angel deluded them." - Epistle of Barnabas, Chapter 9
"“Jews shall be condemned to confiscation of property as well as to perpetual exile, If it shall be established that they have circumcised a man of our Faith or ordered him to be circumcised.” – Emperors Honorius and Theodosius II
“It is unnecessary and indeed unlawful for the faithful to be circumcised” - Venerable Bede (Ecclesiastical History of the English People)
“Wherefore, when the truth is revealed, circumcision is a senseless figure and shade." – St John of Damascene
"But someone might say: “Is there so much harm in circumcision that it makes Christ’s whole plan of redemption useless? Yes, the harm of circumcision is as great as that." - St John Chrysostom
