Reform Judaism has been making efforts to become stronger in ritual observance over the past few years, but as a paradigm, the Pittsburgh Platform of 1885 still is followed by many.
Can you point to something in halakha which says a woman can’t wear tefillin? It certainly didn’t bother Shaul haMelech, or the Rambam, or the Baalei haTosafot.
An interesting fact: Rabbi Dr. David Ellenson, who is a scholar of repute on topics pertaining to German Neo-Orthodoxy, was raised Orthodox. He says that his father encouraged him to attend HUC and take a Reform pulpit because he’d make much more money in a Reform place than as an Orthodox rabbi. To this day, he is a shomer shabbat and a relativsly observant man.
HUC-JIR even employs 2 Orthodox professors: Rabbi Dr. Michael Chernick (teaches Talmud at HUC NY, was a student of Rav Soloveitchik, and was involved in Edah) and Lynn Kaye (attended the GPATS program at Stern College, and was formerly at Shearith Israel).
