What’s the difference between sisters and nuns?

You’ve may have heard these terms used interchangeably, but there are a few key differences.

Nuns are contemplatives, meaning that they are living, praying and ministering while cloistered in a convent or monastery.

Sisters are apostolic, meaning that they are living, serving and praying out in the world. In the spirit of our founders, we, too serve the needs of the times wherever we are called.

Where do sisters live?

When you become a sister, you choose a living situation that best serves both the ministry and the needs of the community. While some of us live alone, others live together in houses or apartments, or convents and other communities. Many of our sisters live in the St. Louis area, but we have sisters in various regions all over the country as well.

Will I earn money or own a car?

In accordance with our vow of poverty, sisters who earn a salary contribute it to a common fund. This sharing of resources means that every sister is actively participating in our commitment to act for justice with a preferential option for the poor.

We’ll budget financial support for everything you need including things like a car, computer and other items for life and ministry. Like many of our sisters, you might find that you enjoy this simplicity of lifestyle freeing, because you can better focus on your mission and your community!

Can I be a sister if I’ve had a relationship with a partner?

Relationships and sexual relations in your past are not of primary concern. What matters most is that you are capable of dedicating yourself to continue the mission of God while sharing life and prayer with the members of the community.

Those seeking membership in a religious community must have the capacity and willingness to lead a chaste, celibate life going forward.

Why don’t you wear habits?

At our founding in 1650 France, our early sisters needed to figure out how they could work freely in society that prescribed limiting roles to women. The answer was in their attire!

By dressing like widows, they were able to work in public without being accompanied by their husband, father, brother or son. And although what they wore was merely a means to enable them to do their good works, it symbolized their mission to be one with those they served.

Eventually, this style of dress evolved into a uniform habit. After Vatican II in the 1960s, religious communities were called to examine how they could best meet the needs of the modern world while also keeping with the spirit of their founders. For the Sisters of St. Joseph, that meant adopting the dress of the times as to not be separated from the neighbor whom we serve.
