AC 6587 - the internal of the church is willing good from the heart

AC 6587 [3]
The internal of the church consists in willing good from the heart,
and in being affected with good;
and its external consists in doing it,
and this according to the truth of faith which the man knows from good;
but the external of the church consists in the devout performance of rituals,
and in doing works of charity, according to the precepts of the church.
From this it is evident that the internal of the church
is the good of charity in the will.
Therefore when this ceases, the church itself also ceases,
for the good of charity is its essential.
External worship indeed remains afterward, as before,
but then it is not worship, but a rite,
which is preserved because it has been so appointed;
but this rite, which appears like worship, is like a shell without a kernel,
for it is an external which remains wherein is no internal.
