...lobbying from a "creationist" group denouncing a Catholic booklet which affirms that it is possible to accept some form of evolution and still believe in the Creator. The lobby group seems to me rather panicky, and also confused and angry. They should calm down. A Christian can accept something of the evolutionary theory - it doesn't neccesarily contradict Genesis. This is a point that Pope Benedict has made more than once, and incidentally which Bl.John Henry Newman also made, writing in 1868, “the theory of Darwin, true or not, is not necessarily atheistic; on the contrary, it may simply be suggesting a larger idea of divine providence and skill.”
The new Youth Catechism produced for WYD tackles this rather well, affirming "God created the world out of nothing. He is Lord of history. He guides all things and can do everything. How he uses his omnipotence is of course a mystery...The sentence 'God created the world' is not an outmoded scientific statement. We are dealing here with a theo-logical statement, therefore a statement about the divine meaning and origin of things..."
YouCat has a Foreword by the H.Father and everyone attending WYD gets a copy. It is competently written and doesn't "talk down" to the young or attempt to be super-cool, it doesn't talk in jargon or assume its readers are stupid. It gives the Church's message and does so with confidence. Recommended.
