MicRho is an annual retreat for freshmen and sophomores focused on fellowship, fun, and spiritual growth. Through prayer, adoration, and meaningful activities, students are encouraged to strengthen their relationship with Christ and embrace the challenge of living a virtuous life—all while building community and enjoying time together.

Chi Rho is an annual retreat for juniors and seniors. The 4-day overnight retreat is based in faith, fellowship, and personal growth. Students deepen their relationships with their friends and teachers, while experiencing Christ in a real and personal way. Modeled after the popular Kairos retreat model, Chi Rho also creates an escape from daily life through games, activities, and some special surprises throughout the weekend. Students who have attended once can then apply to become a student leader. 

Since 1990, students and faculty at Our Lady of the Sacred Heart High School have honored the legacy of Felician Sr. Louise Marie Olsofka by participating in the Love Walk for the Poor. Held each year on the Sunday closest to Valentine’s Day, participants brave the cold to walk from the OLSH convent to the Felician Sisters’ cemetery for a blessing, then return to campus to drop off their donations. Walking in the cold carrying their donations is an essential and powerful aspect of this walk as students experience hardships faced by the poor who must carry all their possessions with them. 

OLSH has participated annually in the March for Life in Washington D.C. since the '90s. A group of students and faculty make the pilgrimage to support the Pro-Life movement in January on the anniversary of the Roe v. Wade Supreme Court ruling.

Students attend a four day retreat/conference at Steubenville University where they attend various workshops and listen to speakers. They are given time to meet other youth from around the country who share the Catholic Faith. It is a powerful experience where they can truly meet Christ in the Sacraments and grow in fellowship with those around them.

The Felician Sisters sponsor a week-long retreat in the summer called Seeds of Hope. The program invites sophomore and junior girls from the Felician sponsored high schools to come together for a week of fun, prayer, and service. The retreat is held in Holly, MI and students apply to attend. Each winter, a representative of the program visits OLSH to share about the experience with our girls and encourages them to apply. Interested young women must apply in the winter before the summer they hope to attend.  Past attendees serve as mentors and leaders on the experience and several OLSH alumni have been selected to serve as leaders.

World Youth Day is celebrated internationally with young people from every continent gathering with the Pope every 2-3 years. The young adults celebrate their faith with the Pope and with each other. Participants experience life the way it is lived in the host country and learn how other Catholics live their faith. World Youth Day is an unforgettable adventure! OLSH students are encouraged to travel with their parish or diocesan group.

The Theology department strives to provide a welcoming environment that faithfully transmits the genuine message of Christ and the authentic teachings of the Catholic Church. The Theology curriculum adheres to the Catholic Bishops Framework for Catholic Education. Yearly topics include the life and teachings of Jesus Christ, The Mission of the Church, the Sacraments, Catholic Social Teaching, and more. Students are required to take 4 years of Theology classes at OLSH. Honors Level classes are available junior and senior years.

Students have the opportunity to attend Adoration and receive the Sacrament of Reconciliation weekly with the OLSH Chaplain. The chapel is available for private prayer for students and faculty throughout the day and theology classes often make time for visits during class periods.

Students are encouraged to participate in the celebration of the Mass. Opportunities to become lectors, cantors, musicians, altar servers, and Extraordinary Ministers of Holy Communion can be found by contacting the OLSH Campus Minister or Chaplain. 

Students who are interested can meet individually or in groups with the OLSH Chaplain for spiritual direction and prayer. Meetings can be ongoing over the course of the school year or on an as-needed basis.
