It is the duty of the Christian to help all of humanity. To heal the sick, to visit the prisoners, to clothe the naked, to house the homeless; and to assist the very dregs of society.
We Christians even extend the hand of fellowship and love to Calvinists. If God made a man, then it is the duty of the Christian to attempt to help that man, no matter how odious, how execrable, how Reformed that man is. Perhaps you are correct in that God put the Reformed here in order to Judge how Christians behave towards them.
See, this is a good example of our differing styles in posting. I post criticisms of certain beliefs, practices, superstitions.
And you post personally insulting remarks about other people.
Perhaps that's the only way you know how to post.
If so, it is possible to learn to behave civilly on these threads.
Try.
