The Pope has again championed women.

Pope Francis stressed the "fundamental" importance of women in the Roman Catholic Church today, a message hailed as a significant shift from the position of his predecessor Benedict.

Supporters of liberal reform of the Church have called on the Catholic Church to give a greater voice to women and recognize their importance to the largest religious denomination in the world, and some groups call for women to be ordained as priests.

The head of the Women's Ordination Conference, which calls for women to be treated equally in the Church and to be allowed to become priests and bishops, said Francis's words were the most encouraging she had heard in her lifetime, but did not go far enough.

"While the pope was trying to be positive about women's role, where he's actually wrong is that women were actually disciples, like Mary Magdalene," WOC Executive Director Erin Saiz Hanna told Reuters.

"He said women are able to communicate Christ's words, but actually women can't preach so that's a false statement."

The Vatican says women cannot be priests as Jesus Christ willingly chose only men as his apostles. Advocates of a female priesthood reject this position, saying Jesus was merely conforming to the customs of his times.

Francis, elected last month as the first non-European pope in 1,300 years, said women had always had a special mission in the Church as "first witnesses" of Christ's resurrection, and because they pass belief onto their children and grandchildren.
