er is a more grievous sin
than contempt of his command. Now some sins are against the very
person of the commander, such as blasphemy and murder. Therefore
disobedience is not the most grievous of sins.

_I answer that,_ Not every disobedience is equally a sin: for one
disobedience may be greater than another, in two ways. First, on the
part of the superior commanding, since, although a man should take
every care to obey each superior, yet it is a greater duty to obey a
higher than a lower authority, in sign of which the command of a
lower authority is set aside if it be contrary to the command of a
higher authority. Consequently the higher the person who commands,
the more grievous is it to disobey him: so that it is more grievous
to disobey God than man. Secondly, on the part of the things
commanded. For the person commanding does not equally desire the
fulfilment of all his commands: since every such person desires above
all the end, and that which is nearest to the end. Wherefore
disobedience is the more grievous, according as the unfulfilled
commandment is more in the intention of the person commanding. As to
the commandments of God, it is evident that the greater the good
commanded, the more grievous the disobedience of that commandment,
because since God's will is essentially directed to the good, the
greater the good the more does God wish it to be fulfilled.
Consequently he that disobeys the commandment of the love of God sins
more grievously than one who disobeys the commandment of the love of
our neighbor. On the other hand, man's will is not always directed to
the greater good: hence, when we are bound by a mere precept of man,
a sin is more grievous, not through setting aside a greater good, but
through setting aside that which is more in the intention of the
person commanding.

Accordingly the various degrees of disobedience must correspond with
the various degrees of precepts: because the disobedience in which
there is contempt of God's precept, from the very nature of
disobedience is more grievous than a sin committed against a man,
apart from the latter being a disobedience to God. And I say this
because whoever sins against his neighbor acts also against God's
commandment. And if the divine precept be contemned in a yet graver
matter, the sin is still more grievous. The disobedience that
contains contempt of a man's precept is less grievous than the sin
which contemns the man who made the precept, b
