Remember that John Paul II famously scolded and prohibited him from administering the sacraments because of his involvement in socialist politics. Francis rehabilitated him in 2019.
“Christ led me to Karl Marx, I don’t think the Pope [John Paul II] understands Marxism. For me, the four Gospels are all equally Communist. I’m a Marxist who believes in God, follows Christ, and is a revolutionary for the sake of his kingdom.” - Fr. Ernesto Cardenal
