To repeat, this does not mean that truth is the only, or the most important, good. But it is sufficiently important, in a systemic and architectonic way, to make us aware that concern for truth—of the sort that could rightly be characterized as a love of truth—is required by the demands of all the goods, as well as the good of truth itself. So every agent should possess the virtue of truthfulness, and this virtue should include, amongst its constitutive dispositions, a love of truth. And if love of truth is incompatible, for the reasons suggested above, with a willingness to lie, then the lie is, in fact, a violation of the good of truth, just as it is a violation of the goods of personal integrity and sociality. The wrongfulness of lying, even for a good cause, is thus triply confirmed.
Thinking you can establish the gospel of Truth on a foundation of lies is like thinking you can fornicate your way to virginity. It is amazing that Christians have to be told this. Even more amazing that they have to be told this when a) the lies do not in fact save a single life but instead, b) give Planned Parenthood a nice documented record of Christian lying in order to drum up pro-abort zeal and donations. Not only wrong, but stupid and counter-productive. A perfect Faustian bargain.
