Dear Mr Theunissen,
Sorry to have taken so long to answer your letter of July 9th. I was away for a while, and then infernally busy. I seem fated continually to make a fool of myself with creationists. The specific quote you mention, from a letter to Sunderland dated 10th April 1979, is accurate as far as it goes. The passage quoted continues "... a watertight argument. The reason is that statements about ancestry and descent are not applicable in the fossil record. Is Archaeopteryx the ancestor of all birds? Perhaps yes, perhaps no: there is no way of answering the question. It is easy enough to make up stories of how one form gave rise to another, and to find reasons why the stages should be favoured by natural selection. But such stories are not part of science, for there is no way to put them to the test."
I think the continuation of the passage shows clearly that your interpretation (at the end of your letter) is correct, and the creationists' is false.
That brush with Sunderland (I had never heard of him before) was my first experience of creationists. The famous "keynote address" at the American Museum of Natural History in 1981 was nothing of the sort. It was a talk to the "Systematics Discussion Group" in the Museum, an (extremely) informal group. I had been asked to talk to them on "Evolutionism and creationism"; fired up by a paper by Ernst Mayrpublished in Science just the week before. I gave a fairly rumbustious talk, arguing that the theory of evolution had done more harm than good to biological systematics (classification). Unknown to me, there was a creationist in the audience with a hidden tape recorder. So much the worse for me. But my talk was addressed to professional systematists, and concerned systematics, nothing else.
I hope that by now I have learned to be more circumspect in dealing with creationists, cryptic or overt. But I still maintain that scepticism is the scientist's duty, however much the stance may expose us to ridicule.
Yours Sincerely,
