Why did monks and nuns promise to live their entire lives within their religious communities

They needed to live alone to practice Christianity freely

They made a vow to devote their lives to god

They could better provide services to others by living in a religious community

They could no longer own property once they joined the church

All of these reasons could be potential factors for why monks and nuns made the promise to live their entire lives within their religious communities. However, the most fundamental reason is that they made a vow to devote their lives to God. This vow includes renouncing personal possessions, living a life of poverty, and dedicating themselves fully to prayer, contemplation, and serving others within the religious community. By living in the community, they could better fulfill their religious obligations and support each other in their spiritual journey.
