The Nuns have Taken a Vow of Poverty

My dad and two younger sisters are Catholics in the family. Only myself and mum are Protestants. But we believe in the same God. My parents help out every week in Little Sisters of the Poor where the nuns there have taken a vow of poverty - such humble actions on their part. They don't believe in amassing great wealth and certainly don't preach prosperity. They lead a very humble simple life in the organisation helping the aged and sick every day to do the necessary things and to keep them mentally occupied in their golden years.
