CAIRO — The architects of the military takeover in Egypt promised a new era of tolerance and pluralism when they deposed President Mohamed Morsi of the Muslim Brotherhood last summer.

Nine months later, though, Egypt’s freethinkers and religious minorities are still waiting for the new leadership to deliver on that promise. Having suppressed Mr. Morsi’s Islamist supporters, the new military-backed government has fallen back into patterns of sectarianism that have prevailed here for decades.

Prosecutors continue to jail Coptic Christians, Shiite Muslims and atheists on charges of contempt of religion. A panel of Muslim scholars has cited authority granted under the new military-backed Constitution to block screenings of the Hollywood blockbuster “Noah” because it violates an Islamic prohibition against depictions of the prophets.

The military leader behind the takeover, Abdul-Fattah el-Sisi, often appeals to the Muslim majority in a language of shared piety that recalls Anwar el-Sadat, nicknamed the believer president, who invoked religious authority to bolster his legitimacy and inscribed into the Constitution the principles of Islamic law.
