Behind the warring parties — the Russian government and the Ukrainian government — there are, as always, church leaders who legitimize their own party’s war as being just. It has been like this in all wars during the past centuries. The Catholic and Protestant churches were particularly active, as were the Orthodox churches in the Ukraine-Russia war. This is based on the two-sword doctrine of the Catholic Church, according to which there are two swords, one “clerical” and one “secular,” and according to which one sword is to be wielded by the church and the other for the church — by kings and politicians with the approval of the respective priests. This dogma, which to this day has not been revoked, also helps us to better understand the present war.
