Christians faced the specific problem of reconciling capital punishment with the belief in the sanctity of human life. ‘God made man in his own image’ (Genesis). However the Church, from the time of Constantine, found it advantageous to ally itself with the State in order to forward and exploit its influence and authority. This alliance involved the Church in a cruel penal system: in fact, it introduced a new capital crime, heresy. Such disquiet as there was largely went underground. When dissent was expressed, Jesus was called up as an advocate for the cause, not as a missionary for penal reform (his Kingdom was not of this world), but because of his life, teaching, and vision of a New Age. Of our two Italian abolitionists, the devout Catholic Pelli repeatedly invoked the Christian God and the Sermon on the Mount. Earlier it was a Protestant, Sébastian Castellion, who caused a stir. Castellion campaigned fiercely against the criminalization of heresy, following the brutal execution of Michael Servetus, burned at the stake in 1553 in Calvin’s Geneva. Castellion, however, was striking a blow for freedom of belief rather than for the abolition of capital punishment as such.
