The reason why not only infants but all others, are by baptism inserted among Christians in the spiritual world, is, that it is by their religions that peoples and nations in that world are distinguished
from each other. The Christians are in the middle, the Mohammedans are round about them, after them come idolaters of various kinds, and the Jews are at the sides. Moreover, all who are of the same
religion are arranged in societies in heaven in accordance with their affections of love to God and love toward the neighbor, and in hell in assemblies in accordance with affections that are the opposites
of those two loves, that is, in accordance with the lusts of evil. In the spiritual world, by which both heaven and hell are meant, all things both as a whole and in every part, or in general
and in every particular, are most distinctly arranged; upon this distinct arrangement there the preservation of the whole universe depends; and such distinguishing is impossible, unless everyone after
he is born can be recognized by some sign showing to what religious body he belongs. For without the Christian sign, which is baptism, some Mohammedan or some idolatrous spirit might attach himself to
newly-born Christian children, or even to youths, and breathe into them an inclination towards his religion, and thus distract their minds and alienate them from Christianity, which would be a distortion
and destruction of spiritual order.
