ATLANTA, Sept. 19 — The attack in a hotel parking lot here last month was remarkable not only because the victim, Juanita Bynum, is the most prominent black female television evangelist in the country, who is pals with Oprah, admired by Aretha, and who recently signed on to campaign for Obama.

It was shocking, especially to legions of women who had latched onto her message that only chastity and self-respect would bring true love, because the attacker who choked, stomped and kicked her, Ms. Bynum said, was her husband.

The episode has led to debate about domestic violence and how churches, particularly black churches, respond to it.

But it has also raised questions about the trajectory of Ms. Bynum’s career as a woman who called herself a prophetess, and while condemning promiscuity spoke openly about her lust and longing, in what has been called one of the most significant contemporary American sermons. Her struggle struck a chord in many black communities, where marriage rates are notoriously low, and it seemed to culminate in the form of an earthly reward: a televised, million-dollar 2003 wedding to a fellow Pentecostal preacher, Bishop Thomas W. Weeks III, followed by what seemed to be a model marriage.
