I was wrong. The lyrics for this song are played out. However, for reference purposes, one has to refer to George Cardinal Pell's excellent article in the journal First Things, a few quotes of which are cited below:
"Morality matters to all of us. This central fact of human experience is often missed by those who put forward some modern, liberal version of conscience. When approached for moral advice, the reply “just go with your conscience” has the effect of further isolating people, driving them back into themselves just when they have courageously stretched out to find answers. The replacement of Newman’s view of conscience with the liberal version has been a disaster in key areas of human life.
"One place to measure that disaster is in technical thought about moral and religious practice. No one—at least, no Christian—believes conscience simply asserts the first thing that comes into our heads. Conscience looks for real answers to our questions, and where can it look except to the truth? But then the value of conscience surely lies not in conscience itself but in the truth to which conscience looks for answers. It is the truth that is primary, and it is from the truth that conscience takes its value—for the bare fact that something is my private belief has no moral significance whatsoever.
"So why would anyone try to oppose conscience to objective truth? Part of the answer lies in a distorted attitude towards the virtue of tolerance. “Tolerance” is often something of a weasel word. Of course, all human beings should tolerate the foibles and weaknesses of their fellows. But by “tolerance” many now mean “never judging.” And this is a much more debatable proposition. In fact, believers in tolerance themselves usually acknowledge unspoken limits. Tolerance rarely means refraining from judging racists, or sexists, or pedophiles, or political cheats—naturally enough: these are morally wrong and should be judged so. But the contemporary love of tolerance is severely limited. In effect, the only things we must be tolerant of are people’s sexual choices, or perhaps their choices about such life issues as abortion or euthanasia."
