The author of Stand Up For Judas is Leon Rosselson.

In the notes to A Different Kind Of Love Song upon which he recorded the song, Dick Gaughan writes:

I sang this because I felt it was an argument worthy of being heard. As a result of my recording this, I have been accused of being anti-Christian. Complete nonsense. I am not anti-Christian or anti any other set of beliefs; I do, however, have a profound dislike of intolerant dogmatism masquerading as truth and I believe that any body of ideas which objects to examination and discussion of its tenets, and responds to such by demonizing the questioner, is not one which I can take seriously.

It is about interpretations and distortions of Christianity: what has been done in its name and a contrast between whether you are prepared to await a 'reward' in heaven (turning other cheek-ism) or whether you will stand up for a perfect world now.

To tell women that they must conform to oppression and acquiesce to lack of control over their own bodies because it is some god's will (and suits some men) is a negation of a basic human right of over 50% of the human race.
