Though Senior Citizens Fellowship was active at Centre level in Mumbai, the need for a Diocesan level fellowship was felt by senior members of the various centres. The same request was then presented to the then Diocesan Episcopa Rt. Rev. Dr. Thomas Mar Theethos who directed a meeting to be held addressing this cause. The meeting was held on 12th March, 2016 at St. Thomas Mar Thoma Church, Santacruz under the leadership of Rt. Rev. Dr. Thomas Mar Theethos which led to the formation of The Mar Thoma Senior Citizens fellowship, Mumbai diocese. Every member of Mar Thoma Church above 60 years is a member of this fellowship. This fellowship facilitates individual’s upliftment both spiritual and mental, enables to use one’s abilities and their years of experience for well-being of the church. The major activities of the Mar Thoma Senior Citizen Fellowship, of the Mumbai Diocese, include One Day Conference, Welfare activities, webinars, etc.
