FOURTH ARTICLE [I-II, Q. 64, Art. 4]

Whether the Theological Virtues Observe the Mean?

Objection 1: It would seem that theological virtue observes the mean.

For the good of other virtues consists in their observing the mean.

Now the theological virtues surpass the others in goodness. Therefore

much more does theological virtue observe the mean.

Obj. 2: Further, the mean of moral virtue depends on the appetite

being ruled by reason; while the mean of intellectual virtue consists

in the intellect being measured by things. Now theological virtue

perfects both intellect and appetite, as stated above (Q. 62, A. 3).

Therefore theological virtue also observes the mean.

Obj. 3: Further, hope, which is a theological virtue, is a mean

between despair and presumption. Likewise faith holds a middle course

between contrary heresies, as Boethius states (De Duab. Natur. vii):

thus, by confessing one Person and two natures in Christ, we observe

the mean between the heresy of Nestorius, who maintained the

existence of two persons and two natures, and the heresy of Eutyches,

who held to one person and one nature. Therefore theological virtue

observes the mean.

_On the contrary,_ Wherever virtue observes the mean it is possible

to sin by excess as well as by deficiency. But there is no sinning by

excess against God, Who is the object of theological virtue: for it

is written (Ecclus. 43:33): "Blessing the Lord, exalt Him as much as

you can: for He is above all praise." Therefore theological virtue

does not observe the mean.

_I answer that,_ As stated above (A. 1), the mean of virtue depends

on conformity with virtue's rule or measure, in so far as one may

exceed or fall short of that rule. Now the measure of theological

virtue may be twofold. One is taken from the very nature of virtue,

and thus the measure and rule of theological virtue is God Himself:

because our faith is ruled according to Divine truth; charity,

according to His goodness; hope, according to the immensity of His

omnipotence and loving kindness. This measure surpasses all human

power: so that never can we love God as much as He ought to be loved,

nor believe and hope in Him as much as we should. Much less therefore

can there be excess in such things. Accordingly the good of such

virtues does not consist in a mean, but increases the more we

approach to the summit.

The other rule or measure of theological virtue is by comparison with

us: for although we cannot be borne towards God as much as we ought,

yet we should approach to Him by believing, hoping and loving,

according to the measure of our condition. Consequently it is

possible to find a mean and extremes in theological virtue,

accidentally and in reference to us.

Reply Obj. 1: The good of intellectual and moral virtues consists in

a mean of reason by conformity with a measure that may be exceeded:

whereas this is not so in the case of theological virtue, considered

in itself, as stated above.

Reply Obj. 2: Moral and intellectual virtues perfect our intellect

and appetite in relation to a created measure and rule; whereas the

theological virtues perfect them in relation to an uncreated rule and

measure. Wherefore the comparison fails.

Reply Obj. 3: Hope observes the mean between presumption and

despair, in relation to us, in so far, to wit, as a man is said to be

presumptuous, through hoping to receive from God a good in excess of

his condition; or to despair through failing to hope for that which

according to his condition he might hope for. But there can be no

excess of hope in comparison with God, Whose goodness is infinite. In

like manner faith holds a middle course between contrary heresies, not

by comparison with its object, which is God, in Whom we cannot believe

too much; but in so far as human opinion itself takes a middle

position between contrary opinions, as was explained above.
