Christians & Communists Against Jean-Paul Sartre's Existentialism

The Main issue with J.P. Sartre's Existentialism with both Communists and Christians seems to be that that the Communists and Christians do not accentuate enough on individualism compared to the, and that the world is big and hence society must be a whole and equal. Christians believe that life is a gift from God, and hence Sartre's existentialism seems to undermine Christian belief that life is God's gift, when existentialism tends to show reality of life which would show the depressive, bleak, unfair side of life. Sartre believed himself that the Christians believed that existentialism would be denying the existence of God and of God's moral law, and by destroying moral laws would supposedly lead to Anarchy, of which I personally disagree because it would simply impose freedom of thought and choice, but would cause some Chaos by those who devoutly believe in god.

According to the Communists' for a communist state to be established, there is a need for hope, and engagement in political action, and in order for the individual to reach a political movement they need to believe that their actions could be successful and hence the need for hope. Sartre's existentialism does emphasise on the reality of the human race and hence emphasise on anguish, abandonment, and despair which would undermine the needed hope needed to create and uphold a communist political state.

So by the philosophical idealisms of Sartre, both communists and Christians seem to be undermined by the reality of the world compared to the either political or belief system and hence both Christians and Communists claim that existentialism denies any room for solidarity.
