To promote Same Sex Marriage.
This is a serious step - dressing like a nun in public... AND to stand in opposition to Church teaching in an effort to support and promote same sex marriage. This is not dissent, this is rebellion. Gramick has already defied Vatican instructions to cease and desist her leadership role, as well as any involvement with New Ways Ministry and has gotten away with it for many years now. Church leaders sympathetic to gay politics have turned a blind eye. What she is doing today is in open defiance of Church teaching. The Church definitely has jurisdiction over religious men and women, and before exercising canonical disciplines toward secular politicians, it seems to me the Church first and foremost needs to deal effectively with neo-protestant clergy and religious like Jeanine Gramick.
Dissident nun misleads Catholics in Maryland.
At a recent event in Maryland, Sister Jeannine Gramick publicly claimed that the recognition of homosexual unions is an issue of Catholic morality, and that those who oppose it are immoral. This position, she stated, “flows from our own church’s social justice teaching.”
However, her statement is false. The Catechism of the Catholic Church clearly teaches that homosexual vice is “intrinsically disordered” and “contrary to natural law” (2357).
Sister Gramick further states: “... our church leaders have claimed that marriage must be between one man and one woman; that the definition of marriage has always been the same; that it cannot change. Well, this is simply not so,” she said. - Source
And she had the effrontery to wear a veil... So why do I say it that way? Because normally she wouldn't be caught dead in a veil. Orders that have given up the habit believe the veil is sign of suppression and oppression. They normally only resort to it when fund raising or trying to pull off something 'Catholic'.
