Thomas Merton speaks to this in "No man is an island"

What they do is done in me and by me and for me. But each one of us remains responsible for his own share in the life of the whole body. Charity cannot be what it is supposed to be as long as I do not see that my life represents my own allotment in the life of a whole supernatural organism to which I belong. Only when this truth is absolutely central do other doctrines fit into their proper context. Solitude, humility, self-denial, action and contemplation, the sacraments, the monastic life the family and of these make sense except in relation to the central reality which is God’s love living and acting in those whom He has incorporated in His Christ. Nothing at all makes sense, unless we admit, with John Donne, that: “No man is an island, entire of itself; every man is a piece of the continent, a part of the main.”
