I'm not a Catholic, but I wholeheartedly agree with Archibishop John J. Myers' voter's guide with regards to pro-choice candidates.
Cardinal Ratzinger stated that a "Catholic would be guilty of formal cooperation in evil, and so unworthy to present himself for Holy Communion, if he were to deliberately vote for a candidate precisely because of a candidate's permissive stand on abortion." But the question of the moment is whether a Catholic may vote for a pro-abortion candidate for other reasons. The cardinal's next sentence answered that question: A Catholic may vote for a pro-abortion Catholic politician only "in the presence of proportionate reasons."I also made the connection between ritual child sacrifice and abortion. After all, why did ancient civilizations sacrifice their children to their gods if not to provide impetus to their prayers for wealth, long life, and happiness? Precisely the same as modern embryonic research and abortion.
What are "proportionate reasons"? To consider that question, we must first repeat the teaching of the church: The direct killing of innocent human beings at any stage of development, including the embryonic and fetal, is homicidal, gravely sinful and always profoundly wrong. Then we must consider the scope of the evil of abortion today in our country. America suffers 1.3 million abortions each year--a tragedy of epic proportions. Moreover, many supporters of abortion propose making the situation even worse by creating a publicly funded industry in which tens of thousands of human lives are produced each year for the purpose of being "sacrificed" in biomedical research.
Thus for a Catholic citizen to vote for a candidate who supports abortion and embryo-destructive research, one of the following circumstances would have to obtain: either (a) both candidates would have to be in favor of embryo killing on roughly an equal scale or (b) the candidate with the superior position on abortion and embryo-destructive research would have to be a supporter of objective evils of a gravity and magnitude beyond that of 1.3 million yearly abortions plus the killing that would take place if public funds were made available for embryo-destructive research.
Frankly, it is hard to imagine circumstance (b) in a society such as ours. No candidate advocating the removal of legal protection against killing for any vulnerable group of innocent people other than unborn children would have a chance of winning a major office in our country. Even those who support the death penalty for first-degree murderers are not advocating policies that result in more than a million killings annually.
