The Church of South India (CSI) has elected the Rt. Rev. K. Reuben Mark as its new Moderator, culminating a period of legal wrangling and ecclesial uncertainty, following the Supreme Court of India’s decision to void the previous moderator’s election. The CSI Synod, meeting in a special session on July 21, 2025, at Chennai, chose Bishop Mark, the current Bishop in Karimnagar and formerly Deputy Moderator, as the primate of South Asia’s largest Protestant body.

An academic and theologian, Dr. Reuben Mark served as Professor of Homiletics for two decades before his consecration as Bishop in 2015. He has long been recognized for his theological acumen and commitment to ecumenism, notably as a council member at United Theological College, Bangalore. Bishop Mark’s election comes at a time of institutional soul-searching for the CSI, which encompasses over 4 million members.

The voting, conducted under the supervision of administrators appointed by the Madras High Court, saw participation from 318 Synod delegates, including bishops from dioceses across South India—with the sole exception of the South Kerala Diocese, currently unable to convene its council. Mark’s election follows his prior service as Deputy Moderator, a role to which he was elevated in the 2020-2023 triennium.

The call for a fresh election was triggered by a landmark decision in May 2025 by the Supreme Court of India, which ruled the 2020 election of the Most Rev. A. Dharmaraj Rasalam as Moderator unlawful. The Court found that Bishop Rasalam, Bishop in South Kerala, did not meet the constitutional requirement of having at least three years left before retirement at the time of his election, since he turned 67 in 2023. This technical violation rendered his election invalid.

However, the elections for other Synod officers—Deputy Moderator, General Secretary, and Treasurer—were upheld, citing their wide margins of victory and to avoid “greater harm” to the CSI’s 4.5 million members.

The Supreme Court also fuled the amendments raising clergy retirement ages, passed at a 2022 Synod, be frozen, pending further ratification and litigation.It ordered fresh elections for the Moderator, with the process to be overseen by retired High Court judges acting as administrators.

Dr. Mark, though serving as Deputy Moderator during the disputed tenure, was not subject to any disqualification in the court’s ruling. His election on July 21 set forth a six-month interim period for his leadership, as the CSI awaits further legal clarity and, potentially, constitutional reform.

The CSI has weathered months of legal challenges, with its constitutional amendments—especially concerning episcopal retirement age and tenure—sparking widespread debate and litigation. While a single-judge bench of the Madras High Court originally limited relief to the Moderator’s election, a Division Bench later impugned the entire Synod Electoral College. The Supreme Court, however, partially reversed that broader interpretation, upholding the elections of all other officers save for the Moderator.
