Purgatory is a fact. Catholics are REQUIRED to accept Purgatory as a dogma of their faith.
You never hear it preached? It's still there.
You don't like to think about it? It's still there.
How can a merciful and loving God permit such a thing?
HOW COULD HE NOT?
Out of the depths have I cried unto Thee, O Lord: Lord hear my voice.
De profúndis clamávi ad te, Dómine: Dómine, exáudi vocem meam.
Let Thine ears be attentive to the voice of my supplication.
Fiant aures tuae intendéntes: in vocem deprecationes meae.
If Thou, Lord, shouldst mark iniquities, O Lord, who shall stand?
Si iniquitátes observaveris, Dómine: Dómine, quis sustinébit.
But there is forgiveness with Thee: because of Thy law I wait for Thee, O Lord.
Quia apud te propitiátio est: et propter legem tuam sustinui te, Dómine.
My soul waiteth on His word: my soul hopeth in the Lord.
Sustinuit ánima mea in verbo ejus: sperávit ánima mea in Dómino.
From the morning watch even until night let Israel hope in the Lord:
A custodia matutina usque ad noctem: specret Israel in Dómino.
For with the Lord there is mercy, and with Him is plentiful redemption.
Quia apud Dóminum misericordia: et copiósa apud eum redémptio.
And He shall redeem Israel, from all their iniquities.
Et ipse redimet Israel, ex ómnibus iniquitátibus ejus.
This partially indulgenced prayer is Psalm 129, one of the 7 Penitential Psalms, the others being Psalms 6, 31, 37, 50, 101, and 142.
