Hello,

even I´m a huge Snape fan I never saw him as a "nice guy". When I was
reading about the Christening (Harrys baptizm) thing I got a hazardous
idea. We know already there is a redemptive pattern about Snape. He
isn´t a good person, but we now definetly since yesterday that he WAS
a Deatheater (past tense, not present tense).
We know he told DD his story and DD believes it. So what had Snape
told him to convince DD? Which story could have been so strong?

Back to Christening thing. Maybe Snape went to a church of the Muggles
and beg for forgiveness? Maybe he got baptized, maybe he got through a
very old Muggle magic, the baptizm? Honestly now! Wouldn´t that
convince DD that he really had changed?

Please don´t kill me now. But I guess the Baptizm is "Old Magic".
The Holy Water on the forehead symbolizes dying into Christ dead and 
and the resurrection with Christ. It means a the beginning of a New Life.

Maybe this protected Harry when the Avadra Kedavra came in form of the
deadly green flashlight on his forehead. There had been the Holy Water
before, Lily followed a very old Muggle tradition.

Okay, these are my crazy thoughts. Sorry my English isn´t perfect.
