When Calvin appeared as one of the reformers of his time, he was accused of being a schismatic and destroyer of the unity of the church that was ruled by the pope. This article intends to demonstrate that Calvin made the greatest effort to participate in several ecumenical meetings between 1540 and 1556 and played a role in resolving the conflicts that threatened church unity and caused separation. Calvin and all the reformers sincerely believed in the existence of one church. He matched word with action and geared his idealism to the situation as it existed. Therefore, it is true to claim that Calvin had a strong ecumenical spirit.

约翰加尔文的普世活动

当加尔文作为他那个时代的改革者之一出现时，他被指控是教宗统治的教会团结的分裂和破坏者。本文旨在证明加尔文在 1540 年至 1556 年期间尽最大努力参加了几次大公会议，并在解决威胁教会合一和导致分离的冲突中发挥了作用。加尔文和所有改革者真诚地相信一个教会的存在。他将言辞与行动相结合，并将他的理想主义与现有情况相适应。因此，声称加尔文具有强烈的普世精神是正确的。
