This is an excellent article and, if read with an open mind and a heart towards Christ’s Church, ends this debate:
The Church’s Infallible and Immutable Doctrine on Contraception Stands Amid Growing Opposition
Some excerpts:
**Double Effect and Lesser Evil Do Not Apply to Condom Use **
*Moralists present a series of conditions that justify the use of these two principles, but the general rule is that one may never desire an evil end or use an illicit, morally condemnable means to achieve a good. In the former case, one would be choosing evil for evil, and in the latter, one would be accepting that the end justifies the means. In both cases one would be violating the fundamental principle of natural law, “Good is to be done and pursued, and evil is to be avoided.”11
Moreover, one would be rejecting the explicit teaching of Revelation that one may not do evil in order to draw some good from it. Saint Paul teaches: “And why not say – as we are accused and as some claim we say – that we should do evil that good may come of it? Their penalty is what they deserve” (Rom. 3:8).
Choosing an action as the lesser of two evils is not licit if it means choosing between two moral evils, two sins. In the case of physical evils, one may opt for the lesser.12
Thus, the principles of double effect and lesser evil do not apply to the use of condoms, such use being “intrinsically evil.”13*
**Forsaking a Single Moral Teaching Would Destroy Morality **
*However, the truth about the procreative purpose of the sexual act was established not by the Church but by the Author of nature Himself. Thus, the Church has no authority to change this teaching, since She is the guardian and interpreter of natural law, not its author. John Paul II emphasizes this in his document on the Christian family in the modern world:
The Church is in no way the author or the arbiter of this norm. In obedience to the truth which is Christ, whose image is reflected in the nature and dignity of the human person, the Church interprets the moral norm and proposes it to all people of good will, without concealing its demands of radicalness and perfection.17
Furthermore, were the Church to abandon even one principle of the natural or revealed law, She would be rejecting the very foundation of moral law, which is the authority of the legislator, in this case, God, of whose wisdom and will every law is but a reflection, be it through nature or through Revelation. “All laws, in so far as they partake of right reason, are derived from the eternal law,”18 explains St. Thomas Aquinas. “The eternal law is nothing else than the type of Divine Wisdom, as directing all actions and movements.”19 *
