for seminary graduates? From my experience, the sacraments are done during Catholic services held BEFORE the graduation and not typically deliberately open to non-Catholics to share in.

Catholics have very specific rules about communion: the Eucharist and the Sacrament of Penance (Reconciliation). All wine there has been blessed and therefore its use is highly restricted.

Participants must have gone to confession prior to receiving them. Obviously, Catholics can lie about it and others can do so by mistake if they come in off the street but it is highly frowned upon.

From their website:

"The Pontifical College Josephinum hosts its annual Commencement Exercises in May, where degrees are conferred to seminarians. Following the ceremonies, graduation events typically conclude with a public reception or a catered lunch for graduates, their families, faculty, and special guests in the campus refectory and auditoriums.

Graduation & Public Meal Details

Event Structure:

Graduation day traditionally begins with a Baccalaureate Mass, followed by Commencement Exercises.

Public/Guest Meals: Following the ceremony, a reception or celebratory meal is customarily hosted on campus (often in the Msgr. Leonard Fick Auditorium or the main Refectory).

Access: While everyday dining in the refectory is limited to seminarians, staff, and those on meal plans, graduation meals are open to attending families and invited guests."
