Thaddeus Ma Daqin

Thaddeus Ma Daqin (; born 1968, Shanghai, China) is a Chinese Catholic prelate who served as Bishop of Shanghai from 2014 until 2023.

He was appointed as auxiliary bishop with the approval of the Holy See and Chinese Government in July 2012. Daqin announced his resignation from the Chinese government mandated Catholic Patriotic Association at his episcopal ordination Mass, and was taken into custody as a result. The Chinese Government has detained him under house arrest ever since (largely confined to Sheshan Seminary) and has prevented him from carrying out his episcopal duties.

The Chinese government unilaterally appointed a new bishop of Shanghai in April 2023, which the Vatican approved in July 2023.

Early life and priesthood Ma was born in Shanghai and was ordained as a priest in 1994, after graduating from the Sheshan Seminary. He is a former editor of the Shanghai Diocese's Guangqi Press, one of the two main Catholic publishers in the People's Republic of China. He served as head of Shanghai Pudong Deanery and, in December 2011, was appointed as Vicar General by Bishop Aloysius Jin Luxian. The Chinese government claims the authority to approve and appoint bishops.

In 2012, Ma received the approval of both Beijing and the Holy See for appointment as an Auxiliary Bishop of Shanghai.

Ordination as Auxiliary Bishop and House Arrest

Catholic priests and nuns had gathered outside the Cathedral in protest at the participation of Vincent Zhan Silu in the ceremony. Zhan had been appointed "bishop" without the approval of the Vatican, and was loyal to the Patriotic Association. Bishop Jin and two other Vatican affirmed bishops performed the "laying on of hands" ritual to invoke the Holy Spirit during the ceremony. Zhan and two other bishops were also supposed to perform the ritual, but, according to Reuters, Ma "prevented them from putting their hands on his head by rising from his knees and hugging the three bishops instead."

Speaking from the pulpit, Ma then acknowledged the presence of the priests and nuns outside the cathedral, before speaking of the need for him to now focus on the pastoral duties of bishop rather than the bureaucratic duties of a Patriotic Association bishop: "Therefore, starting from this day of consecration, I will no longer find it convenient to be a member of the Patriotic Association," he said. He also refused to share a chalice with a bishop who has been excommunicated by the Roman Church. According to Reuters, Ma soon disappeared from public view, "instructed by the late bishop Aloysius Jin Luxian to move to a mountainside seminary outside Shanghai, where he has been confined... He was stripped of his new title, questioned by officials for weeks and required to attend communist indoctrination classes." That month Reuters reported that Ma remained at the Sheshan Seminary, regularly posting blog items for the faithful: "mostly excerpts from scripture and greetings to his flock." After the death of Nelson Mandela, Ma cited one of the anti-Apartheid leader's most famous quotes: "Freedom is indivisible; the chains on any one of my people were the chains on all of them, the chains on all my people were the chains on me."
