Can a Chrisitan lose his/her salvation?

[Succubus]

Show me where the Trinity is taught in the Bible.  How about the books of the Bible themselves?  Why is the Gospel of Peter not part of scripture?  Or, the Gospel of Thomas?  Or, the Acts of Pilate?

I know Christians are seldom if ever, embarrassed by the unbelievable bullshit that makes up 99% of the bible, but this:

In the text Peter performs miracles such as resurrecting smoked fish, and making dogs talk.

Might be too much even for the fundies. A talking, walking dog, no problem. A resurrected fish? That might be just too much for the poor dears.
