Dude, everytime I read or hear someone state this, showing their total lack of understanding of the trinity doctrine, it makes me laugh my ass off.
LOL !
While I am not a trinitarian ( I don't think that trinity doctrine is needed), that is NOT what it is, nor is that what Christ sacrifice was about, at all.
You know, Sunday school while half asleep doesn't actually equate to knowledge much less understanding of the bible, much less Christian doctrines.
