Page "Christianity and Judaism" Paragraph 56

Christianity usually reserved the death penalty for heresy, the denial of the orthodox view of God's view, and witchcraft or similar non-Christian practices.

For example, in Spain, unrepentant Jews were exiled, and it was only those crypto-Jews who had accepted baptism under pressure but retained Jewish customs in private, who were punished in this way.

It is presently acknowledged by most of Christianity that these uses of capital punishment were deeply immoral.
