Do our Holy Fathers teach that it is an idol? No. Our Holy Fathers Saint John Paul II and Francis refer to it as “Mother Earth” or, in another case, a statue or representation that is not an idol. As anything in creation, it can be idolized (which is a grave sin), but it is not an idol per se.
Pope Francis has already said that the figure of the Pachamama did not have idolatrous intentions.
“Good afternoon, I would like to say a word about the pachamama (mother earth) statues that were removed from the Church at Traspontina, which were there without idolatrous intentions and were thrown into the Tiber.” – (Source).
Now, in 1988, Pope Saint John Paul II made an Apostolic Travel to Uruguay, Bolivia, Lima (Peru) and Paraguay. When he used to get off the plane and stepped on foreign soil, he used to kiss the ground. Was he worshipping the earth? Of course not! To say otherwise is calumny. Not only that, but when he went to Bolivia, most specifically to Valley of Cochabamba and celebrated the Eucharist, he taught the following during his homily regarding the Pachamama:
“Blessed is he who, in any work, seeks God from the heart. Blessed is he who, in the exercise of any profession, seeks the good of others.
I want to address now, from this land of Cochabamba, peasant par excellence, to you, Quechua peasants, men of the “bronze lineage”, who from time immemorial populate these valleys and are at the roots of Bolivian nationality; that you have given to the world your nutritional and medicinal findings such as potatoes, corn and quinoa. The Lord continues to accompany your work with His help. He takes care of the birds of the sky, of the lilies that are born in the field, of the grass that sprouts from the earth (Mt 6, 26-30). This is the work of God, who knows that we need the food that the earth produces, that varied and expressive reality that your ancestors called the “Pachamama” and that reflects the work of divine Providence by offering us His gifts for the good of man.
Such is the deep meaning of the presence of God that you must find in your relationship with the earth, which covers for you the territory, the water, the stream, the hill, the hillside, the creek, the animals, the plants and the trees , because earth is all the work of creation that God has given us. Therefore, when contemplating the earth, the crops that grow, the plants that mature and the animals that are born, raise your thoughts to the God of the heights, the creator God of the universe, who has manifested to us in Christ Jesus, our Brother and Savior. That way you can reach Him, glorify Him and thank Him. “Because the invisible of God, since the creation of the world, [His] intelligence is revealed through his works” (Rm 1:20).
“Blessed is he who … rightly administers his affairs; the righteous will never falter ”(Ps 112 , 5-6). Blessed is he who strives in his work, despite the difficulties of the environment. Blessed is he who seeks to build the civilization of love with his work.” – (May 11, 1988).
His entire homily can be read here. There is no English translation in the Vatican website, so the above is my translation from the Spanish.
Pope Saint John Paul II refers to Pachamama as “Creation”, “Mother Earth”. Not an idol.
