Galatians 5:3

That you may not suppose that this is spoken from ill-will, I say not to you alone, he says, but to every one who receiveth circumcision, that he is a debtor to do the whole Law. The parts of the Law are linked one to the other. As he who from being free has enrolled himself as a slave, no longer does what he pleases, but is bound by all the laws of slavery, so in the case of the Law, if you take upon you a small portion of it, and submit to the yoke, you draw down upon yourself its whole domination. And so it is in a worldly inheritance: he who touches no part of it, is free from all matters which are consequent on the heirship to the deceased, but if he takes a small portion, though not the whole, yet by that part he has rendered himself liable for every thing. And this occurs in the Law, not only in the way I have mentioned, but in another also, for Legal observances are linked together. For example; Circumcision has sacrifice connected with it, and the observance of days; sacrifice again has the observance both of day and of place; place has the details of endless purifications; purifications involve a perfect swarm of manifold observances. For it is unlawful for the unclean to sacrifice, to enter the holy shrines, to do any other such act. Thus the Law introduces many things even by the one commandment. If then thou art circumcised, but not on the eighth day, or on the eighth day, but no sacrifice is offered, or a sacrifice is offered, but not in the prescribed place, or in the prescribed place, but not the accustomed objects, or if the accustomed objects, but thou be unclean, or if clean yet not purified by proper rules, every thing is frustrated. Wherefore he says, "that he is a debtor to the whole Law." Fulfil not a part, but the whole, if the Law is of force; but if it be not of force, not even a part.
