Summary: The Westminster Confession of Faith (completed 1646 by the Westminster Assembly) is
the mature confessional statement of Reformed teaching on the soul after death. Chapter XXXII, "Of the
State of Men after Death, and of the Resurrection of the Dead," makes three claims in one paragraph: the
soul neither dies nor sleeps but at death immediately returns to God; the righteous are received
into the highest heavens and the wicked are cast into hell; and — pointedly — "besides these two places …
the Scripture acknowledgeth none." This is the settled Reformed denial of any intermediate compartment:
no Abraham's bosom as a waiting-room third place, no limbo, no purgatory. There are two destinies
only, entered at once.
The bodies of men, after death, return to dust, and see corruption; but their souls (which neither die nor sleep), having an immortal subsistence, immediately return to God who gave them.
— Westminster Confession of Faith, XXXII.1, creeds.net. Against soul-sleep on the one hand and any delay on the other, the Confession affirms that the soul, immortal in subsistence, passes to God the moment the body dies — carrying forward the conscious-survival doctrine that Calvin had defended in Psychopannychia.
The souls of the righteous, being then made perfect in holiness, are received into the highest heavens, where they behold the face of God in light and glory, waiting for the full redemption of their bodies; and the souls of the wicked are cast into hell, where they remain in torments and utter darkness, reserved to the judgment of the great day.
— Westminster Confession of Faith, XXXII.1, creeds.net. The righteous behold God's face now, while still "waiting for the full redemption of their bodies" at the resurrection — so the intermediate state is genuinely intermediate, yet already glorious. There is no purgatorial cleansing first: the righteous are "then made perfect in holiness" at death itself.
Besides these two places for souls separated from their bodies, the Scripture acknowledgeth none.
— Westminster Confession of Faith, XXXII.1, creeds.net. This single clause is the Reformed rejection of the whole medieval geography in one stroke: no limbus patrum, no limbo of children, no purgatory, no third "Abraham's bosom" holding-place — only heaven and hell, entered immediately at death.
