Dr. Peter Kreeft is a Catholic theologian of the Thomist tradition. Last Spring he delivered a lecture at Southeastern Baptist Theological Seminary in Wake Forest, North Carolina (Yes, a Roman Catholic addressing Baptists!). The title of his lecture was “Will There Be Sex in Heaven?,” and this lecture is one you will not want to miss.
The short answer he gives to the question in the title is “yes.” The answer is “yes” mainly because gender distinctions continue in the new creation. The resurrection of the body is a restoration project, not an obliteration of something so deep as our maleness or femaleness. Thus gender complementarity will always be a part of us, even in the age to come.
In any case, you can listen to the entire lecture for yourself at Southeastern’s chapel audio page (February 3, 2007). The lecture actually comprises the gist of a chapter in Kreeft’s book about heaven. So a text version of the lecture is available here: “Is There Sex in Heaven?” I’ll be interested to read your responses.
