The article on Intermediate State sounds pretty close to Catholic belief, IMHO. There are difference between the two views.
"in purgatory the souls of those 'who died in the charity of God and truly repentant, but who had not made satisfaction with adequate penance for their sins and omissions,' are cleansed after death with punishments designed to purge away their debt." - Second Vatican Council, "Sacred Liturgy", "Apostolic Constitution on the Revision of Indulgences", no. 3
Roman Catholics believe that Christians may have to suffer in Purgatory before going to Heaven in order to complete the atonement for their sins. Protestants believe that it is appointed for men to die once and after that comes judgment. We do not see any biblical justification for a purgatory and instead go directly to Paradise or hell awaiting final judgment into the lake of fire.
God telling Moses, "Take full vengeance for the sons of Israel on the Midianites; afterward you will be gathered to your people" (Num 31:2) is a source of comfort. God will gather us all to our own people immediately and we will be at rest. It is not a time of separation but of fulfillment.
"You guide me with your counsel, and afterward you will take me into glory. Whom have I in heaven but you?" - Psalms 73:24-25
