Whoever shall now contend that it is unjust to put heretics and blasphemers to death will knowingly and willingly incur their very guilt.
To 'justify' means nothing else than to acquit of guilt him (her) who was accused as if his own innocence were confirmed.
Surely in Judas' betrayal it will be no more right, because God both willed that his Son be delivered up, and delivered him up to death, to ascribe the guilt of the crime to God than to transfer the credit for redemption to Judas.
