Beyond Belief: A Buddhist Critique of Christianity, by A. L. de Silva. The host (The Buddhist Society of Queensland) comments,
This is the electronic version of a Book printed in Sri Lanka. It is reproduced here to make its contents known more widely. The original book contains no mention of publisher or of a copyright notice. Little is known about the author.
I’m not so sure that “little is known about the author”. A little googling finds De Silva described as “an Australian convert to Buddhism” and a “distinguished Theravadan scholar”. His Homosexuality and Theravada Buddhism is widely available on the web.
