Martin Luther's realization that the church could not be reformed from within and his commitment to schism were gradual processes that developed over time. Luther's initial intention was to reform the Catholic Church from within, and his criticisms of its practices and doctrines were initially directed at specific issues such as indulgences and the authority of the Pope. However, as his ideas spread and his conflicts with church authorities intensified, Luther became increasingly disillusioned with the Church and its hierarchy. The turning point for Luther was likely the Diet of Worms in 1521, where he was called to recant his views but refused, famously stating, "Here I stand, I can do no other, God help me." This defiance led to his excommunication from the Catholic Church, and he subsequently founded his own church, which became known as the Lutheran Church. Thus, while there was no specific moment when Luther realized the impossibility of reforming the Church from within or committed to schism, his experiences and conflicts over the years led to his eventual break with the Catholic Church and the creation of a new religious movement.
