Pope Francis calls for greater dialogue and cooperation between Christians, Marxists

Yeah, except Jesus was essentially teaching socialism:

40 “The King will reply, ‘Truly I tell you, whatever you did for one of the least of these brothers and sisters of mine, you did for me.’

41 “Then he will say to those on his left, ‘Depart from me, you who are cursed, into the eternal fire prepared for the devil and his angels. 42 For I was hungry and you gave me nothing to eat, I was thirsty and you gave me nothing to drink, 43 I was a stranger and you did not invite me in, I needed clothes and you did not clothe me, I was sick and in prison and you did not look after me.’

44 “They also will answer, ‘Lord, when did we see you hungry or thirsty or a stranger or needing clothes or sick or in prison, and did not help you?’

45 “He will reply, ‘Truly I tell you, whatever you did not do for one of the least of these, you did not do for me.’

You might be confusing it with communism, which seems like it cannot be implemented without totalitarianism. The totalitarianism is what makes it a bad political system and we are shown that we don't need communism for totalitarianism. Best example of that is currently Russia.

It's scary that there are actually people who call themselves Christians and are attracted to such oppressive system.
