NEW YORK (JTA) — In the early 1970s, while I was CEO of the Seagram Company, public dialogue about gay rights was largely nonexistent in corporate America. Social discourse had not yet even evolved into the “don’t ask, don’t tell” ethos that dominated the following decades. Homosexuality was simply not discussed and therefore, by implication, was shameful.

During that time, as the head of a company with thousands of employees, personnel issues often came across my desk. One day, the director of human resources came into my office with a recommendation to terminate one of my brightest executives. I found myself puzzled that anyone would want to fire such a promising young man until the director leaned in and confided in a hushed tone, “Well, you know, he’s a homosexual.”

The declaration did persuade me — but not in the way he had hoped.

The promising young executive continued on to a distinguished career at Seagram, and the HR director was soon let go. Although my choice was shocking to the director, the decision was obvious to me: to fire a person because of their sexual orientation was not only wrong, it was bad business. It was discrimination, plain and simple, and would not be tolerated in the company I ran.

More than 40 years later, I still feel such discrimination to be unequivocally wrong, but my views on the subject of gay rights have evolved. Particularly today, as we celebrate the U.S. Supreme Court’s decision to recognize the legality of gay marriage, I now see marriage equality as a moral imperative because of my Jewish roots.

Just as the high court has shown moral bravery in its recognition of gay marriage, the Jewish community should follow its example in our myriad communities. As Jews, we should remember that our tradition upholds the bond between two loving people and the families they create as a source of strength and commitment to the betterment of the world.

“Justice” is a word we are taught early in life, and we are reminded constantly that it is a principle we should uphold and promote. In Hebrew, the word tzedek is used to promote acts of loving kindness and righteousness. Its diminutive, tzedakah, is translated as charity, but it is much more. We are taught in the Torah, in the book of Deuteronomy 16:20: “Justice, Justice shall you pursue.” In Hebrew, “Tzedek, tzedek tirdorf.”

It is a vital, active imperative for the Jewish people to be on the front lines of issues protecting and promoting the rights of any group being treated unfairly. To take approximately 10 percent of the U.S. population and tell them they are second-class citizens is clearly unjust. As Jews we are instructed to seek justice for the stranger, the widow and the orphan because too often society discriminates against and takes advantage of those without advocates.

I have come to see the protection of gay marriage as a manifestation of the Jewish value of seeking justice for those who are enslaved. To those who cover their prejudice with reference to biblical injunctions against homosexuality, I ask if they are willing to live by every other law listed in the Torah. For such literalists, I submit that the very Torah portion of Leviticus that they so often quote also enjoins us to harbor no hatred against our brother and our neighbor.

To freeze Judaism in time because of ancient biblical edicts is to deny that Judaism is a mighty river that moves forward through time, a living entity that changes course and becomes renewed through what it meets on the banks. Like a river, it retains its essential character although it is constantly renewed and evolving.

Today, the Jewish pursuit of justice must channel itself against the denial of marriage equality. For Jews, who have suffered so much throughout history at the hands of prejudice, to stand idly by while any group is treated so unfairly is unequivocally wrong.

I have been inspired in my thinking on gay rights and marriage equality by a woman I have known since she was a teenager. She is now the leader of Keshet, a group that promotes equality for the LGBT community in the Jewish world.

Idit Klein first came to my attention when she was in high school. She was a student on a program I founded called the Bronfman Youth Fellowship that targets Jewish teens of exceptional promise from an array of backgrounds. In my conversations with her over the years, I have learned that the issues facing LGBT Jews are ones on which all Jews need to speak out.

Within the Jewish community we must endeavor to include and celebrate the diversity of families and couples within all aspects of religious, communal and institutional life. When our communities continue to open their tents as our forefather Abraham did, to include all who wish to participate in Jewish life, our people’s possibilities expand and gain strength.
