Objective truth

In Installment number 34, the Laws of God, Father Benedict Groeschel again talks about the natural law. He talks about reading about an "ethics" committee doing something against the natural law:
"Some ethics committees loudly supported the idea of partial birth abortion. That is hypocrisy. That is a misuse of the term."

Fr. Groeschel goes on to talk about Pope John Paul II's encyclical, Veritatis Splendor encylical (the Splendor of the Truth):
"what the pope is ultimately saying is...that there are objective, solid, basic, moral truths that do not change. I have to say that God went out of his way to make that very clear..."

Fr. Groeschel ends with:
"Objective truth can defeat evil and in fact, it is ultimately the only thing that can defeat evil. It is the truth of God."
