He also served as a Shaliach ("emissary") in Boston, Buffalo, Newark, and New Haven, establishing Yeshiva Achei T'mimim elementary schools for both boys and girls.
Hecht led protests against the film Monty Python's Life of Brian, claiming that it "was produced in hell."
He worked to raise awareness of the Seven Universal Laws of Noah (Sheva Mitzvoth Bnei Noach) in greater society.
Hecht was featured in a June 23, 1995, article by Larry Yudelson, for his assertion, at a rabbinical gathering, that Jewish Law (Halakha) could permit the assassination of Israeli Prime Minister Yitzhak Rabin and Foreign Minister Shimon Peres for their proposal at Oslo to withdraw from parts of the West Bank and the Gaza Strip.
After the assassination, Hecht was placed on a six-month paid leave by his synagogue and was, along with six other American Jews, barred for "security" reasons by the Israeli government from entering the country.
