North­eastern University’s Center for Spir­i­tu­ality, Dia­logue, and Ser­vice held an inter­faith vigil in the Sacred Space on Tuesday after­noon to mark the one-​​year anniver­sary of the Boston Marathon bomb­ings and to remember those affected by the tragedy.

About 60 people attended the remem­brance cer­e­mony, some don­ning Boston Strong t-​​shirts or Boston Marathon jackets in a show of solidarity.

In his remarks, North­eastern Pres­i­dent Joseph E. Aoun reminded those in atten­dance that many people are still recov­ering from the attacks of April 15, 2013.

This is not a reli­gious ser­vice. This is a human ser­vice that has brought us all here today,” Aoun said. “That day is going to stay with us for­ever. Many mem­bers of the Boston com­mu­nity are still strug­gling with what hap­pened and our role is to be there for each other.”

Alexander Lev­ering Kern, the center’s exec­u­tive director, began the vigil by noting the solemn feeling in the city’s atmos­phere on Tuesday. “Every­where there are quiet markers of the marathon, large and small,” he said. “It is right and good for us to look back lest we forget. Of course, we can’t forget.”

After a moment of silence, a bell was rung four times in honor of the four people who were killed by the bomb­ings or in the wake of the attack. Martin Richard, Lu Lingzi, and Krystle Camp­bell were killed in the explo­sions on Boyl­ston Street on April 15, and Mass­a­chu­setts Insti­tute of Tech­nology police officer Sean Col­lier was killed by the bombing sus­pects during an ambush on April 18, according to law enforce­ment authorities.

During the vigil, two of the center’s spir­i­tual advisers shared their expe­ri­ences from that tragic day a year ago.

Har­rison Blum, the Bud­dhist spir­i­tual adviser, was serving as chap­lain at Brigham and Women’s Hos­pital on Marathon Monday. He said he wit­nessed a score of self­less acts that day, including emer­gency room patients allowing vic­tims be treated before them and people bringing in dough­nuts and coffee for the hos­pital staff.

I some­times say that hos­pital chap­laincy is the front lines of chap­laincy,” Blum said. “On that day it felt like it was chap­laincy in the front lines.”

Kaitlin Ho, the Inter­var­sity Multi-​​Ethnic Chris­tian Fel­low­ship spir­i­tual adviser, was vol­un­teering at the finish line when the bombs went off. “Everyone was looking at each other and searching each other’s faces for what to do,” she said. “There was this shared sense of con­fu­sion and fear.”

Run­ning shoes were set up on a table in the Sacred Space. Patrick Reyes, pro­gram man­ager of Spir­i­tu­ality, Edu­ca­tion and Dia­logue, noted that they served as a reminder of Boston and Northeastern’s resiliency and that the com­mu­nity con­tinues to bear the pain of April 15. Some of the atten­dees were given white roses, which they placed on top of the shoes.
