"Pachamama is a goddess revered by the indigenous peoples of the Andes. In Inca mythology she is an "Earth Mother" type goddess, and a fertility goddess who presides over planting and harvesting, embodies the mountains, and causes earthquakes. She is also an ever-present and independent deity who has her own creative power to sustain life on this earth. Her shrines are hallowed rocks, or the boles of legendary trees… Priests sacrifice offerings of llamas, cuy (guinea pigs), children (The Capacocha Ritual) and elaborate, miniature, burned garments to her. Pachamama is the mother of Inti the sun god, and Mama Killa the moon goddess. Mama Killa is said to be the wife of Inti." (Pachamama - Wikipedia)
I don’t know what that sounds like to you, but that sounds like any other pagan goddess and idol to me. And regardless of our personal opinions or attitudes, holy tradition is not ambiguous with respect to the gods of the nations:
For all the gods of the Gentiles are devils, but the Lord made the heavens (Psalm 96:5).
For although there may be so-called gods in heaven or on earth—as indeed there are many “gods” and many “lords”—yet for us there is one God, the Father, from whom are all things and for whom we exist, and one Lord, Jesus Christ, through whom are all things and through whom we exist (1 Cor 8:5-6).
They did not destroy the peoples, as the Lord commanded them, but they mixed with the nations and learned to do as they did. They served their idols, which became a snare to them. They sacrificed their sons and their daughters to the demons; they poured out innocent blood (Psalm 106:34-38).
They stirred him to jealousy with strange gods; with abominations they provoked him to anger. They sacrificed to demons that were no gods, to gods they had never known (Deut 32:16-17).
For you provoked your Maker with sacrifices to demons and not to God; You forgot the eternal God who nourished you, and you grieved Jerusalem who nurtured you (Baruch 4:7-8).
What do I imply then? That food offered to idols is anything, or that an idol is anything? No, I imply that what pagans sacrifice they offer to demons and not to God. I do not want you to be participants with demons. [The following words are significantly relevant in the context of this idol in a Roman church.]
You cannot drink the cup of the Lord and the cup of demons. You cannot partake of the table of the Lord and the table of demons. Shall we provoke the Lord to jealousy? Are we stronger than he? (1 Cor 10:20-22)
There is
zero justification for an idol of a pagan goddess—to whom children have been sacrificed—to be placed on an altar consecrated for the worship of the only true and all-pure God and Lord of hosts.
Wherefore the worship of all demons would be inconsistent in us who worship the supreme God; and the service of demons is the service of so-called gods, for “all the gods of the pagans are demons.” Hence we are determined to avoid the worship of demons even as we would avoid death; and we hold that the worship, which is supposed among the Greeks [or the indigenous people of the Andes]
to be rendered to gods at the altars, and images and temples, is in reality offered to demons. (Origen, Against Celsus 7.69)
To think of all the martyrs who refused to offer so much as a tiny pebble of incense at the altar of a false god, lying in the catacombs of Rome, above which a Christian church places not mere incense, but the false god itself on its very altar. Again the words of the Apostle ring loudly:
Shall we provoke the Lord to jealousy? Are we stronger than he?
Or at least that's where we're coming from.
