A four-day long missionary symposium was one of the long awaited moment of MSMHC during the platinum Jubilee year. The symposium was solemnly inaugurated by Sr. Philomena Mathew, the Superior General on 5 November after a meaningful Holy Mass celebrated by Fr. Johnson Parackal SDB, Executive Director of DBI, Guwahati. 

The forum opened a setting conducive for serious study and reflection as it had a series of sessions on selected topics by different resource persons. Earnestly desiring to bring about a radical renewal, around 280 members participated in the event, reflecting on MSMHC life and mission. Most of the papers were presented by the MSMHC Sisters who made genuine efforts to enlighten the members on the life and mission. There were also papers by a few eminent persons who are among the close associates of the MSMHC. They helped in gaining a deeper understanding on the need for bringing adequate changes.  

On the final day of Symposium, the participants were enthralled by the Opera presented by the Novices from Mary Immaculate Novitiate, Mawroh on the life of Bishop Stephen Ferrando.
