35 We have said that the State must not absorb the individual or the family; both should be allowed free and untrammelled action so far as is consistent with the common good and the interest of others. Rulers should, nevertheless, anxiously safeguard the community and all its members; the community, because the conservation thereof is so emphatically the business of the supreme power, that the safety of the commonwealth is not only the first law, but it is a government's whole reason of existence; and the members, because both philosophy and the Gospel concur in laying down that the object of the government of the State should be, not the advantage of the ruler, but the benefit of those over whom he is placed. As the power to rule comes from God, and is, as it were, a participation in His, the highest of all sovereignties, it should be exercised as the power of God is exercised - with a fatherly solicitude which not only guides the whole, but reaches also individuals.
