I think he would have been appalled at what the church was doing, ie. The crusade's, especially the crusade against the Cathars. Also the so called holy inquisition.
In my opinion, he would have been horrified at what was being done in his name. For instance, in January 1208, Pierre de Castinau is murdered, allegedly by Cathar supporters. Pope Innocent lll calls for a crusade against the Cathars. November 1208, the Pope issues a papal bull offering indulgences and land redistribution for the crusaders.
In spring 1209 Simon de Montfort leads an army south. July 22nd they sack Beziers and massacre the population, between 15,000 and 20,000 are killed. The papal representative is told that there are Catholics living there and he utters that famous phrase, " kill them all, God will know his own " The crusade carries on with even more atrocities committed until almost all Cathars are wiped out, what would Jesus have said about that.
The first crusade was another atrocity instigated by the Roman Catholic Church, it began in 1096 and it took till 1099 to arrive at and besiege Jerusalem. When the city fell there was a massacre of the inhabitants, Jews, Moslems and Christians were killed in their tens of thousands.
What indeed would Jesus have thought about a church which, in his name, had committed such atrocities. I will leave that to whoever reads this.
More to come.
