Is the Truth Always Simple?

In their book Roman Catholics and Evangelicals: Agreements and Differences, Protestant authors Norman Geisler and Ralph MacKenzie quip that Catholicism “has no widely circulated equivalent to ‘The Four Spiritual Laws’ or other simple plan of salvation” (page 234).

The comment seems to imply that in order for something to be true, it must be simple. Complex ideas that can’t be explained in four easy steps must therefore be false. But the claims that truth is always simple and complexity means falsehood is rubbish. Is trigonometry false because it is complex?

To the charge that Catholics lack a “simple plan of salvation”, I point to these resources that do a fine job succinctly explaining salvation from a Catholic perspective:

• The Catholic Information League provides evangelistic comic tracts on various topics. One entitled “Salvation Sound Bites (from the Catholic Catechism)” is especially clear and concise. Dave Armstrong has written a few and he lists endorsements of these tracts from Karl Keating, Fr. Peter Stravinskas and others (look under the “Catholic Organizational Affiliations” subheading in his literary resume).
• Catholic Answers has an excellent outreach brochure named “God’s Love for You” that is widely circulated in print and available on their web site. See also their resource “How to Become a Catholic”.

More similar resources exist, but these are a few that came to mind. Feel free to post others in the comments if you have some to recommend.
