Class One. Beis Hamikdash and Nevua was real giluy and Hislabshus. It needed Korbonos to affect this.  

Class Two. The unfinished part of Pada BiShalom. Even in Golus there can be Giluy Elokus, but not through Mimalei and Korbonos but in Sovev (Atzmus) and Teshuva and higher Tefilla GaMaCh and Torah.
