“One of “Reformed” Christianity’s many ills: setting the Incarnate God against His Mother.”
Yeah, because we wouldn’t want anyone to think that Mary is in any way inferior to her God.
She is, and the Catholic Church is the first to acknowledge it. In the first paragraph of Pope Blessed Pius IX's solemn declaration of the doctrine of the Immaculate Conception
From the very beginning, and before time began, the eternal Father chose and prepared for his only-begotten Son a Mother in whom the Son of God would become incarnate and from whom, in the blessed fullness of time, he would be born into this world. Above all creatures did God so love her that truly in her was the Father well pleased with singular delight.
