Also...Of the Catholic schools that were left open how many of the students are Catholic? How many are non-Catholic? And...Of those who are not Catholic, how many later convert to Catholicism? Is the Catholic Church neglecting the evangelizing of the Catholic children living in the suburbs.
Were you aware that in Wichita, Kansas, that all Catholic children are offered a tuition-free Catholic K-12 education? If they can do this, why aren't other Catholic dioceses?
Finally....It is my opinion, for Christians of all denominations, that the **most** important mission field is one’s **own** children first. The next most important mission field is the children of their congregation. When those two areas are fully attended to then they can spend time and resources on other missionary work.
It's not required but it is recommended often.
