In your opinion, can a Christian believe in universal salvation?

[Okay, maybe Mike Johnson is a competent parliamentarian.]

I'm something akin to what RI calls a "Purgatorial Universalist", although I try to be careful to think of it as something that I hope is true rather than assert outright. I understand the free will argument and think that it does make sense, but I also think that it's pious and charitable to maintain that hope.
