Parish Boundaries & Catholic Social Teaching

"In canon law, a Catholic belongs to the parish in the territory of which he resides. There are exceptions to that, notably 'personal parishes,' in which the parish includes those in certain 'personal' categories, such as language, ethnicity, associations, campus, professions or liturgical traditions.... The Sunday Mass obligation can be fulfilled anywhere. Yet canon law does not really envision living in one parish and never worshipping there. It is, though, the new reality" (Father Raymond J. de Souza, National Catholic Register, 4/25/24)

Are some very practical benefits of parish boundaries going overlooked?  When we are not conscious of boundary lines, isn't it easier for inactive Catholics and others to go unnoticed? 

"orthodox Catholic social teaching is based on a deeply realistic understanding of man's nature as fallen. For two millennia, the Church has taught that man has a hardwired inclination to sin that, unchecked, leads to drunkenness, envy, lust, selfishness, and a host of other sins. Such a disordered life undermines community and leads to self-destruction. But Catholic doctrine also holds that man possesses the freedom, with the help of God's grace, to master unruly passions and follow the moral teachings of the Church, beginning with the Ten Commandments, and so to live a life of inner peace in responsible community with other men. It is this unambiguous moral inheritance—a time-tested recipe for reducing poverty and other social ills as well as nurturing fulfilled lives—that Catholic Charities today has lost sight of in its turn to the state as the primary solution for society's pathologies" (Manhattan Institute, Winter 2000).

In most situations, parish boundaries strike me as vital to promoting community and being neighbors to each other.
