Setting aside the fact that the Bible says nothing about Baptism for the dead, I believe such an ordinance is unnecessary and thus pointless.
But than again it does not matter what you and I think is nescessary or not it is the Lord's plan that man is too fulfill.
The point is I know of nothing in the Bible that even implies such a thing is necessary for the fulfillment of God’s plan. Couple that with the fact that the Bible does not even mention it, and it becomes irrelevant, so far as I am concerned.
Or to give my view on that more clearly...
It is an imagined solution to an imagined problem.
I am as concerned about it as I am with worrying about whether Santa Clause has a pilots licence.
