Because “Life with Christ is a wonderful adventure.” – Pope St. John Paul II

As our youth embark on their transformative journey at Camp Cana, let us lift them up in prayer.

May the Holy Spirit guide their hearts, open their minds, and fill them with the light of Christ as they experience this life-changing week.

They left for the retreat on Monday after attending Mass in the Chapel.

As prepares for Vacation Bible School, June 15-19, our 45 dedicated teen helpers gathered in prayer and preparation, ready to guide 105 campers as they discover the beauty of God’s creation and the depth of His love.

Together, we will step into Rainforest Falls—a world alive with God’s handiwork, where every waterfall, towering tree, and vibrant creature reminds us of His presence. Through stories, songs, and service, our children will learn what it means to be deeply rooted in a relationship with Christ, finding strength and hope even in life’s storms.

Honoring and Remembering Veterans on Memorial Day

extends our heartfelt thanks to John Roth of the VFW Post 5077, whose compassionate act of draping the graves of over 100 veterans at Assumption Cemetery reminds us of the enduring power of remembrance and community. Each flag placed is a symbol of hope, unity, and the promise that these heroes are never forgotten.

As Memorial Day approaches, let us lift our hearts in prayer—not only for those who have fallen, but for all veterans and their families. May their courage inspire us to live with purpose, kindness, and a commitment to peace.

Memorial Day Prayer
God of Power and Mercy,
You destroy war and put down pride. Banish violence from our midst and wipe away our tears, that we may all deserve to be called your sons and daughters.

Embrace in your mercy those men and women who have died in the cause of freedom, and bring them safely into your kingdom of justice and peace.

Grant us the wisdom to honor their memory, the strength to carry forward their legacy, and the grace to be instruments of your love in the world.

We ask this through Christ our Lord. Amen.

May this Memorial Day fill our hearts with gratitude, hope, and a renewed spirit to serve one another in love.

Please Note: There is NO 6:30AM Mass in the Church on Memorial Day and the Parish Office is CLOSED.

Congratulations and Blessings to Monsignor Dennis Stehly for celebrating 49 years of priesthood today.We ❤ you!
