One who is separated can confer a sacrament even as
he can have it." But the power of conferring a sacrament is a very
great power. Therefore schismatics who are separated from the Church,
have a spiritual power.

Obj. 3: Further, Pope Urban II [*Council of Piacenza, cap. x; cf.
Can. Ordinationes, ix, qu. 1] says: "We command that persons
consecrated by bishops who were themselves consecrated according to
the Catholic rite, but have separated themselves by schism from the
Roman Church, should be received mercifully and that their Orders
should be acknowledged, when they return to the unity of the Church,
provided they be of commendable life and knowledge." But this would
not be so, unless spiritual power were retained by schismatics.
Therefore schismatics have spiritual power.

_On the contrary,_ Cyprian says in a letter (Ep. lii, quoted vii, qu.
1, can. Novatianus): "He who observes neither unity of spirit nor the
concord of peace, and severs himself from the bonds of the Church,
and from the fellowship of her priests, cannot have episcopal power
or honor."

_I answer that,_ Spiritual power is twofold, the one sacramental, the
other a power of jurisdiction. The sacramental power is one that is
conferred by some kind of consecration. Now all the consecrations of
the Church are immovable so long as the consecrated thing remains: as
appears even in inanimate things, since an altar, once consecrated,
is not consecrated again unless it has been broken up. Consequently
such a power as this remains, as to its essence, in the man who has
received it by consecration, as long as he lives, even if he fall
into schism or heresy: and this is proved from the fact that if he
come back to the Church, he is not consecrated anew. Since, however,
the lower power ought not to exercise its act, except in so far as it
is moved by the higher power, as may be seen also in the physical
order, it follows that such persons lose the use of their power, so
that it is not lawful for them to use it. Yet if they use it, this
power has its effect in sacramental acts, because therein man acts
only as God's instrument, so that sacramental effects are not
precluded on account of any fault whatever in the person who confers
the sacrament.

On the other hand, the power of jurisdiction is that which is
conferred by a mere human appointment. Such a power as this does not
adhere to the recipient immovably: so that it does not remain in
heretics and schi
