Spiritual Weapon, Bless, Haste and You...

[Sentack]

Okay, this is a strange question and I'm pretty sure I know the answer but I have to ask because it came up in a session and not everyone was convinced how to rule this question.

Does the weapon summoned by Spiritual Weapon gain the benefits of Bless and/or Haste? Does it matter when Bless or Haste was cast? (Before SW or after SW is summoned?)

What do people think?

I think the general concensus is no as spiritual weapon is a lingering spell and not an actual summons.
