Many People have over time pondered and asked many questions as to how Catholic Nuns get to settle their livelihood bills, feed, etc since the church doesn’t pay them any regular fixed salary.
The Catholic Nuns just like other religious are not on any salary scale of the Church but are allowed to work at other institutions such as Schools, Orphanages, Hospitals, etc in order to get paid. That is why most of the nuns are practitioners or experts in educations, home and child-care, nursing and some even doctors, etc. These are the various channels through which they can get paid in order to meet certain needs of theirs. Although traditionally, in some parishes some nuns are helped with monthly stipends by the parish.
Nuns just like Congregational priests belongs to various congregational Orders by virtue of their religious profession; this simply implies that they technically own nothing to oneself. Everything one nun owns belongs to the congregation for a the general benefits of others. So the Nuns are taken good care of by the congregations which are high supported by the church itself.
So, the Nuns are catered for by their congregation and they earn from other institutions where they work.
