Rabbi Barnett Brickner sits, frowning in his study at Temple Judea of Massapequa, N.Y. He's been asked his opinion of the proposed new "platform" of Reform Judaism, which comes up for a vote next May at a national convention of Reform rabbis. The platform says that the Torah was revealed by God at Sinai and that its commandments "call to us even though we live in modernity." It urges Reform Jews to pray daily, to make the Sabbath a holy day, to follow dietary laws, and more. Brickner is alarmed.
