In May 1922, Vvedensky and group of priests named the Living Church () were brought to Moscow with the assistance of the
GPU. Vvedensky and two others met on May 10 in the
Grebnevsky Church on
Lubyanka Square with the church's
pastor, fr. . They agreed to collaborate for the support among the Moscow clergy. Simultaneously supporting Archbishop Antonin Granovsky, the head of the movement to gain adherents in the provinces. The other goal of their agenda was to arrange the meeting with the Patriarch Tikhon in an effort to end what they saw as counterrevolutionary activity on the part of the Church. They typed up an appeal at the
Revolutionary Military Council which was certified by
Trotsky's personal secretary and, on May 12, distributed by
Stalin to the
Politburo, which approved it – in fact, the only type-written archival copy was signed by Stalin,
Zinoviev,
Kamenev,
Molotov,
Mikhail Tomsky, and
Aleksey Rykov. The same evening of the Politburo meeting, Vvedensky with several other renovationist priests confronted Patriarch
Tikhon, at that time under his
house arrest, with evidence that his anti-Soviet activities were leading to chaos in the Church. Tikhon denied such anti-Soviet activity, but readily agreed to step down from the
patriarchal throne, and handed authority temporarily over to Metropolitan Agathangel (Preobrazhensky) of
Yaroslavl until the new council could be convened to elect a new patriarch. Several days later, they got Tikhon to agree that the patriarchal chancellery should be run by the Living Church priests, yet he stipulated to have that be overseen by other two
bishops. However, upon leaving the meeting, Vvedensky reported publicly that the Patriarch had approved the 1923 renovationist's local council as being the proper church administration until the local council could be convened for the election of a new Patriarch. Bishop Antonin (Granovsky) was proclaimed the president of the
Supreme Ecclesiastical Administration () with Vvedensky as the vice-president. When Vvedensky met with Metropolitan
Benjamin (Kazansky) of Petrograd in late May, the metropolitan refused to accept the Supreme Ecclesiastical Administration as the rightful administration of the church without direct instructions from the Patriarch. In a letter to all parishes in his diocese, Metropolitan Benjamin forbade Vvedensky and other renovationist priests from performing the
sacraments before they had repented before him. That led to the arrest of Metropolitan Benjamin the next day after the letter was released, and Vvedensky's presence at that arrest was compared with
Judas Iscariot at the arrest of Christ. Bishop
Alexy (Simansky), who temporarily managed the diocese during the absence of Metropolitan Benjamin, restored Vvedensky and the others to their rights on June 4 under the pressure from the GPU, which threatened to execute Benjamin. He was supposed to be a witness for the prosecution against Metropolitan Benjamin, but at the very beginning of the trial he was wounded in the head by a stone thrown at him. After that, he dropped out of church life for 2 months. Returning to activity, he discovered a sharp antagonism between the two leaders of the Renovationist schism - Metropolitan Antonin (Granovsky) and
Vladimir Krasnitsky. This conflict led to a split in the "Living Church". Metropolitan Antonin (Granovsky) on 20 August 1922 creates another association within Renovationist schism, named "Union for Church Revival". After the failure of negotiations with Antonin (Granovsky), Vvedensky created Renovationist association, named "
Union of the Communities of the Ancient Apostolic Church" (SODATs), headed it, wrote its program documents, and thanks to his fame, he contributed to the opening of its branches in many regions of the USSR. ==Vvedensky as Head of the Living Church, 1923-1946==
