Women have been elected heads of national governments on six continents. They have flown into space, served in elite combat units and won every category of Nobel Prize. The global #MeToo movement, in 15 months, has toppled a multitude of powerful men linked to sexual misconduct.

Yet in most of the world’s major religions, women remain relegated to a second-tier status. Women in several faiths are still barred from ordination. Some are banned from praying alongside men and forbidden from stepping foot in some houses of worship altogether. Their attire, from headwear down to the length of their skirts in church, is often restricted.

But women around the world in recent months have been finding new ways to chip away at centuries of male-dominated traditions and barriers, with many of them emboldened by the surge of social media activism that’s spread globally in the #MeToo era.

Millions of women in India this month formed a human wall nearly 400 miles long in support of women who defied conservative Hindu leaders and entered an important temple that has long been off-limits to women and girls between the ages of 10 and 50.

In Israel, where Orthodox Judaism has long restricted women’s roles, one Jerusalem congregation has allowed women to lead Friday evening prayers. Roman Catholic bishops, under pressure from women’s-rights activists, concluded a recent Vatican meeting by declaring that women, as an urgent “duty of justice,” should have a greater role in church decision-making.

Many feminist scholars are challenging the rightfulness of long-standing patriarchal traditions in Christianity, Judaism and Islam, calling into question time-honored translations of verses in the Bible, Torah and Quran that have been used to justify a male-dominated hierarchy.

Social media is seen as a big catalyst in boosting activism and forging solidarity among women of faith who seek more equality. The #MeToo movement has been evoked – even in the ranks of conservative U.S. denominations – as a reason why women should expect more respectful treatment from male clergy, and a greater share of leadership roles.

“Women are looking for opportunities to have their voices heard and be more effective in their religious traditions,” said Gina Messina, a religion professor at Ursuline College in Ohio who describes herself as both a feminist and a Catholic theologian. “Using social media is an opportunity to say what they think.”

She co-founded a blog called Feminism and Religion that has scores of contributors around the world and followers in more than 180 countries. She also co-edited a collection of essays by Christian, Jewish and Muslim women explaining why they haven’t abandoned their patriarchal-leaning faiths.

“The perception seems to be that it is a feminist act only to leave such a religion. We contend that it is also a feminist act to stay,” the three editors write in their foreword.

Here’s a look at the status of gender equality in some of the world’s religions:

ROMAN CATHOLICISM

Catholic doctrine mandates an all-male priesthood, on the grounds that Jesus’ apostles were men.

A decades-long campaign for women’s ordination has made little headway and some advocates of that change have been excommunicated. Women do play major roles in Catholic education, health care and parish administration

While the recent meeting of bishops at the Vatican produced a call to expand women’s presence in church affairs, no details were proposed. The seven nuns who participated along with 267 male clergy were not allowed to vote on the final document.

ISLAM

Some of the most important traditions and practices of the Prophet Muhammad were preserved and carried forth by the women closest to him– his wives and daughters. But as with many other major faiths, women in Islamic tradition have largely been relegated to supporting roles throughout recent history.

Women in Islam do not lead prayer or give traditional Friday sermons. In larger mosques where women are welcome, they are almost always segregated from men in the back or allocated spaces on other floors with separate entrances and exits.

JUDAISM

The gender situation within Judaism is markedly different in Israel and the United States, which together account for more than 80 percent of the world’s Jewish population.

The largest U.S. branches, Reform and Conservative, allow women to be rabbis, while the Orthodox branch does not. In Israel, the Conservative and Reform movements are small, and Orthodox authorities hold a near monopoly on all matters regarding Judaism.

One major source of contention: the Orthodox-enforced policy of prohibiting women from praying alongside men at the Western Wall in Jerusalem, the holiest site where Jews can pray. Numerous women protesting the policy have been arrested, and several American Jewish groups were angered last year when Israel’s government backtracked on plans to expand a space where both men and women could pray.

However, there have been moves to expand Orthodox women’s roles in religious life. A Jerusalem congregation, Shira Hadasha, has adopted a liberal interpretation of Jewish religious law that incorporates women’s involvement in services, such as leading Friday evening prayers and reciting from the Torah on the Sabbath.

MORMONISM

Women in the Mormon church are barred from being priests, leading local congregations or holding the top leadership posts in a faith that counts 16 million members worldwide.

The highest-ranking women in the church oversee three organizations that run programs for women and girls. These councils sit below several layers of leadership groups reserved for men.

The role of women in the conservative religion, officially named The Church of Jesus Christ of Latter-day Saints, has been a subject of debate for many years, with some members pushing for more equality and increased visibility for women.

The church has made some changes in recent years. But the church shows no signs of budging on women’s ordination.

HINDUISM AND BUDDHISM

The gender-equality situation in these two Asian-based faiths is difficult to summarize briefly. Neither has a single supreme entity that enforces doctrine, and each has multiple branches with different philosophies and practices.

In Buddhism, women’s status varies from country to country. In Thailand, a Buddhist stronghold, women can become nuns – often acting as glorified temple housekeepers – but only in 2003 won the right to serve as the saffron-robed full equivalents of male monks, and still represent just a tiny fraction of the country’s clergy.

In India, the Supreme Court recently lifted a ban on women at the historic Sabarimala temple. Some Hindus consider menstruating women to be impure. But most temples remain dominated by men.

SOUTHERN BAPTISTS

While many Protestant denominations now ordain women, the largest in the U.S. – the Southern Baptist Convention – does not. It advocates that women submit to male leadership in their church and to a husband’s leadership at home.

Southern Baptist leaders say this doctrine aligns with New Testament teaching.
