I answer that, "State," properly speaking, denotes a kind of position, whereby a thing is disposed with a certain immobility in a manner according with its nature. For it is natural to man that his head should be directed upwards, his feet set firmly on the ground, and his other intermediate members disposed in becoming order; and this is not the case if he lie down, sit, or recline, but only when he stands upright: nor again is he said to stand, if he move, but only when he is still. Hence it is again that even in human acts, a matter is said to have stability (statum) in reference to its own disposition in the point of a certain immobility or restfulness. Consequently matters which easily change and are extrinsic to them do not constitute a state among men, for instance that a man be rich or poor, of high or low rank, and so forth. Wherefore in the civil law [*Dig. I, IX, De Senatoribus] (Lib. Cassius ff. De Senatoribus) it is said that if a man be removed from the senate, he is deprived of his dignity rather than of his state. But that alone seemingly pertains to a man's state, which regards an obligation binding his person, in so far, to wit, as a man is his own master or subject to another, not indeed from any slight or unstable cause, but from one that is firmly established; and this is something pertaining to the nature of freedom or servitude. Therefore state properly regards freedom or servitude whether in spiritual or in civil matters.
Reply Obj. 1: Uprightness as such does not pertain to the notion of state, except in so far as it is connatural to man with the addition of a certain restfulness. Hence other animals are said to stand without its being required that they should be upright; nor again are men said to stand, however upright their position be, unless they be still.
Reply Obj. 2: Immobility does not suffice for the notion of state; since even one who sits or lies down is still, and yet he is not said to stand.
Reply Obj. 3: Duty implies relation to act; while grades denote an order of superiority and inferiority. But state requires immobility in that which regards a condition of the person himself. _______________________
SECOND ARTICLE [II-II, Q. 183, Art. 2]
Whether There Should Be Different Duties or States in the Church?
Objection 1: It would seem that there should not be different duties or states in the Church. For distinction is opposed to unity. Now the faithful of Christ are called to unity according to John 17:21, 22: "That they . . . may be one in Us . . . as We also are one." Therefore there should not be a distinction of duties and states in the Church.
Obj. 2: Further, nature does not employ many means where one suffices. But the working of grace is much more orderly than the working of nature. Therefore it were more fitting for things pertaining to the operations of grace to be administered by the same persons, so that there would not be a distinction of duties and states in the Church.
Obj. 3: Further, the good of the Church seemingly consists chiefly in peace, according to Ps. 147:3, "Who hath placed peace in thy borders," and 2 Cor. 13:11, "Have peace, and the God of peace . . . shall be with you." Now distinction is a hindrance to peace, for peace would seem to result from likeness, according to Ecclus. 13:19, "Every beast loveth its like," while the Philosopher says (Polit. vii, 5) that "a little difference causes dissension in a state." Therefore it would seem that there ought not to be a distinction of states and duties in the Church.
On the contrary, It is written in praise of the Church (Ps. 44:10) that she is "surrounded with variety": and a gloss on these words says that "the Queen," namely the Church, "is bedecked with the teaching of the apostles, the confession of martyrs, the purity of virgins, the sorrowings of penitents."
