At the heart of who we are is our name, Holy Union.

We express this union first of all by being one with ourselves. We strive to bring this union to our world by working among different cultures, ethnic groups, the deprived and marginalized. We strive to respect and care for the earth.

The Holy Union Sisters are an international congregation of Catholic women religious who minister today on four continents. We wear a cross with the Latin words, Sancta Unio inscribed on the front, as a symbol of our internationality. It reminds us of the desire of our founder, Jean Baptiste Debrabant, who in a letter to the sisters in 1842, wrote of the special significance of our name: "You have received that name only that you may form all together a union of heart, mind and affection in Jesus and Mary."

World Water Day - March 22

As members of UNANIMA International, Holy Union Sisters observe days designated by the United Nations.

World Water Day, on 22 March is about taking action to tackle the water crisis. Today, there are over 663 million people living without a safe water supply close to home, spending countless hours queuing or trekking to distant sources, and coping with the health impacts of using contaminated water.
The Sustainable Development Goals, launched in 2015, include a target to ensure everyone has access to safe water by 2030, making water a key issue in the fight to eradicate extreme poverty.
