Perhaps the best answer is to be found in the manifestos published by the American Humanist Association since 1933 (Manifesto I).
Small excerpt from
Humanist Manifesto II (1973):
Too often traditional faiths encourage dependence rather than independence, obedience rather than affirmation, fear rather than courage. More recently they have generated concerned social action, with many signs of relevance appearing in the wake of the "God Is Dead" theologies. But we can discover no divine purpose or providence for the human species. While there is much that we do not know, humans are responsible for what we are or will become. No deity will save us; we must save ourselves.
Humanism is dependent on the paradigm that there is no god who can offer salvation, nor can these people determine a divine purpose from a God they claim doesn't exist. It gets better:
Promises of immortal salvation or fear of eternal damnation are both illusory and harmful.
Now compare this to everyone's favorite passage from
John 3:16-19:
16: For God so loved the world, that he gave his only begotten Son, that
whosoever believeth in him should not perish, but have everlasting life.
17: For God sent not his Son into the world to condemn the world; but that the world through him might be saved.
18: He that believeth on him is not condemned:
but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God.
19: And this is the condemnation, that light is come into the world, and men loved darkness rather than light, because their deeds were evil.
I hope it becomes apparent that Humanism, itself a body of religious thought rooted in Darwinism, is incompatible with any form of Theism, including the Judeo-Christian worldview.
