Our Mission Statement: 
Love God, Love People, Make Disciples

Our Vision Statement:

We aspire to be a healthy, loving and growing faith community that brings people to Christ
and the Eucharist, and forms missionary disciples to send them out to transform our
communities. Every member is highly valued, and committed to worship, grow, serve,
connect and give freely.


Welcome to the Catholic Community of Sts. James, Cornelius & Cyprian!

One’s first impressions of visiting a new place can be life-changing for any person. When I first arrived at St. James, Mason at the end of August, 2010, I was very impressed by the beauty of the church surroundings, gardens, flowers and more so the friendliness of the people. I truly felt this was my home and it still feels that way today!

When we clustered with Sts. Cornelius & Cyprian in October of 2015, I was a little apprehensive about how I will be received as a foreign-born priest in that small, country parish. Much to my surprise and amazement, at 7:30 am on that early Sunday morning, there was standing room only in their beautiful church; from little children with their parents, teenagers, young adults and the elderly they were all there to welcome me and celebrate our first Mass together. I truly felt this was my home too and it still feels that way today!

On July 1st, 2018 St. James and Sts. Cornelius & Cyprian were merged into a single parish to make us build a strong, vibrant new community of faith. As pastor of this new community, I welcome you and hope that you too will find a new home as you come visit us. On behalf of our entire new parish community, I hope you will find welcome, joy and happiness!

Disciple Maker Index Survey

Parish Survey

Sts. James, Cornelius & Cyprian will be participating in a parish survey about discipleship conducted by the Catholic Leadership Institute! We need your help! Please help us by participating in a 10-15 minute survey online. The survey can be accessed at from February 8th through March 1st and will ask you to reflect on your own spiritual growth and enable you to provide feedback on our parish’s    efforts to help you grow. All responses will be confidential and the parish will only receive information about the community as a whole.

We are trying to get the highest response rate possible. This information will be invaluable to Fr. Kusi and our various ministries as we plan for the future and strive to be the best disciples we can be. We will receive the results this spring/summer at which time we will share what we have learned with the entire parish.

If you don’t use the computer, there will be opportunities to complete the survey after daily and Sunday Mass and you can obtain a paper copy by contacting Alison at 517.676.9111.

Thank you for helping with this important project!
