The problem here is that the general attitude the Pope expresses towards business and capitalism is much older than Marx. In fact, it arguably goes all the way back to the founding of the Church, and most certainly was prevalent during the Middle Ages.
Not all who are skeptical towards business or capitalism are Marxists.
True. I was raised Catholic. I left more than one Parish because of Priests constantly preaching social justice.
They would read the Sacred Scriptures with no real passion. However, when they got to the Homily they would come alive with social justice garbage.
They had an inner anger that was revolting. There are many in the Church doing the work of Satan.
However, to give Popes, Priests and Pastors a pass because they are not trained in the economic sciences is too easy. The question to ask is this, does the Church (all churches) think that thous shall not steal is not an absolute commandment? Does it need an asterisk after it in the bible? Because forcible taking property from one person is a sin even if the proceeds go to notable cause. It is still a sin even if one steals from another under the guise of democracy.
I would go even further, does the church support covenanting your neighbors possessions? Because this is the tool of the left all over the world to work the poor up to support leftist/progressive/socialist policies. Jesus was well aware and taught the covenanting led to stealing and saw no difference between the sins.
