I’m no fan of Lincoln, but that is a lie.
The claim that Lincoln regularly read Marx, or picked up economic doctrines from Marxist writings, is entirely anachronistic. Marx did not publish the first volume of his treatise Capital until 1867, some two years after Lincoln was assassinated. His earlier writings on the relationship between capital and labor primarily appeared in obscure European outlets with little circulation in North America, and even the Communist Manifesto of 1848 went almost completely unnoticed in the English-speaking world until sometime after 1870. https://www.aier.org/article/was-lincoln-really-into-marx/
Let me quote the text, he says nothing of the sort.
“Beware of the dogs, beware of the evil workers, beware of those who mutilate the flesh! For we are the circumcision, the ones who worship by the Spirit of God, exult in Christ Jesus, and do not rely on human credentials” Philippians 3:2-3 NET
He just said it isn’t needed for Salvation, but never calls it barbaric or hints it to be.
You say that like it is a bad thing.
