So Christians call it 'mother' and really mean it? I don't think that is a Christian idea. Sorry. As for the Pope's statement on anything economic, lefties need not apply. The US is suffering under them now, they have no economic ideas worth anything, for them it is about power.
Its an analogy! Like all analogies, it is imperfect.
Nice straw man. The Earth, which God created, has characteristics that are similar to a mother. Again, an analogy.
Perhaps you should take time and read the following “Centesimus Annus,” also Pope John XXIII, “Mater et Magistra.” Don’t forget the granddaddy of them all, “Rerum Novarum”, by Pope Leo XIII
Finally:
“Among the actions and attitudes opposed to the will of God, the good of neighbour and the ‘structures’ created by them, two are very typical: on the one hand, the all-consuming desire for profit, and on the other, the thirst for power, with the intention of imposing one’s will upon others.” (John Paul II, encyclical letter Sollicitudo Rei Socialis, n. 37.)
In all cases, the Holy Fathers are teaching the primacy of the human person, and their God-given dignity. No system, whether capitalism, Marxism, socialism, etc., works or is just, if it doesn’t focus on the human person. Additionally, other Popes speak out against Marxism because of its rejection of private property.
