    Confirmation Journey | Grade 9
    Sundays | September 10–December 17 | 7:00–8:45 p.m.
    Oak Brook

    Confirmation Journey 2023 | Grade 9

    Sundays, September 10–December 17 | 7:00–8:45 p.m.
    Confirmation Service | Saturday, January 20, 2024 | 3:00 p.m. | Oak Brook

    Confirmation is an annual experience for our students in grade 9 where they have an opportunity to deepen and proclaim their Christian faith. Confirmation is not mandatory, and students have the freedom in this program to explore the basics of the Christian faith, understand the theological traditions of their faith, and decide if they want to publicly proclaim that faith.

    We believe that students learn best through personal engagement with mentors and small groups, so this program is structured to provide a small group of their peers who are guided by an adult mentor. Mentor groups will meet weekly in connection with our larger High School community (Koinonia) and will process the Confirmation curriculum together with their group. Confirmation mentors are parents and other adults who love young people and are coached and trained to have conversations about life and faith with adolescents.

    Parent support and investment in Confirmation is essential and we invite every family to encourage their student in this experience. For parents to be equipped to engage with their Confirmand, there is a mandatory parent AND student meeting at 5:45–6:45 p.m. on Sunday, September 17. 

    We know that family life is hectic and that wonderful activities like music, theater, dance, and sports fill our schedules. The opportunity to deepen and confirm our faith is significant and we ask that families make every effort to attend our mandatory Confirmation meetings and the Fall Retreat. Life happens so there is some flexibility, but we ask that students not miss more than two meetings throughout the Confirmation experience.

    Register your student for confirmation using the link above. However, if you have already registered for Sunday/Wednesday Koinonia and indicated that your student wants to participate in Confirmation then you do not need to register again.

    Please reach out to Mandy at mjanuszewski@ChristChurch.us with any questions.

    Fall Retreat 2023

    October 20–22 | Covenant Harbor, Lake Geneva, WI

    Fall Retreat is a weekend away at Covenant Harbor that offers students time to rest and recalibrate amid their hectic school and extra-curricular schedules. This weekend is often celebrated as the highlight of our students’ years as they can move away from the many distractions of their weekly lives and fully focus on their friendships in this community and space to worship and connect with God. 

    Students meet at the Oak Brook campus in the early evening on October 20 and take coach buses up to Covenant Harbor in Lake Geneva, WI. After enjoying a weekend of fun and friendship as well as worship and teaching, they will return to the Oak Brook location in the afternoon of October 22. This weekend is a ‘can't miss’ for any high school student!

    If you have questions about the Fall Retreat, please reach out to Emily Maruyama at emaruyama@ChristChurch.us

    Contemporary or Classic Worship
    Worship With Us!

    Sundays 9:00 & 10:45 a.m. (year round)

    Worshipping as a part of a larger community is significant for the spiritual developlment of an adolescent. Research suggests that high school students who were regularly part of an ongoing worshipping community were more likely to maintain their faith beyond high school. At Christ Church, we are eager to help our students develop not only in their peer communities, but as part of the wider church. We encourage students to sit with their families for worship or, feel free to join other students who sit together. Our staff and volunteers attend worship and are eager to help studnets connect with one another or to sit with a student who may not be attending with their family. If you have any questions about Sunday morning worship, please contact Emily | emaruyama@ChristChurch.us
