Children's Liturgy of the Word (CLOW) — Make the Word Come Alive for Our Kids!

Each Sunday at our 5:00 PM Mass, children in Kindergarten through 2nd Grade are invited to participate in Children's Liturgy of the Word (CLOW).

During this special time, our youngest ...parishioners hear and explore the same Scripture readings as the rest of the parish community—presented in a way that is engaging and meaningful for them. Through age-appropriate storytelling, discussion, and reflection, children don't just hear God's Word; they interact with it, ask questions, and carry its message home in their hearts.

We need you! This beautiful ministry is seeking warm, enthusiastic volunteers to help lead our young disciples in breaking open the Sunday Scriptures. No theology degree is required—just a love for our faith and a heart for children. Training and all materials are provided. Interested in learning more? Contact: goodnod@stjohn23rd.org or call 262-284-2102.

Help us nurture the faith of our youngest parishioners—one Sunday at a time.

School may be out, but we are always proud of our students! ❤️

Congratulations to our final Mission Award recipients of the 2025-26 school year — and this time, our staff joined in the fun too! Students wrote awards for teachers and staff, sharing words of gratitude, encouragement, ...and appreciation for all they do.

It was a wonderful reminder that our mission is lived out every day through kindness, service, leadership, and faith. We are so proud of these students and grateful for the incredible staff who help them grow.

Rain will NOT stop us. What. A. Day.
It wouldn’t have been possible without Mrs. Lippe, Jenn, Erica, Kristin, and Joni. Thank you for pivoting and absolutely nailing it.
Until August, SJ23…✌🏻

And just like that… another school year comes to a close.

As summer begins, we hope our students and families take time to slow down, rest, recharge, and enjoy every moment together. Sleep in a little, soak up the sunshine, make memories, and enjoy all the simple joys this season ...brings. Thank you for sharing your year with us — for the laughter, learning, growth, friendships, and countless moments that made this year so special. We are incredibly grateful for our SJ23 community.

Have a safe, relaxing, and joy-filled summer break. We can’t wait to see you again soon! ☀
