I am afraid it is Martin Stern who has misunderstood the talmudic reference ( Letters, September 25). Since it was mortally dangerous in talmudic times to attempt to convert, so much the more reason in those times to have a “cooling-off period”. It made sense. But no, halachah is very clear.
As far as converting for the reasons of marrying a Jewish partner, why not? I do not in any sense condone marrying out but, apart from the practical fact that we need to introduce fresh genes, it is better to try to gain a Jew than to lose one.
Finally, the demand for a lengthy process in order for the prospective convert to “prove” himself is simply not halachic. I suggest Mr Stern rereads the talmudic reference. David Kanareck Russell Grove London NW7 3QU
