Here I thought I was being generous because I merged tongues and interpretation into one.:)The bible makes a difference between knowledge and understanding:
Pr 4:7
Wisdom is the principal thing; therefore get (1)wisdom: and with all thy getting get (2)understanding.
Let's do a complete breakdown with that in mind:
1 Corinthians 12:8 "For to one is given
by the Spirit the
(1)word of wisdom;
(2)to another the word of knowledge by
the same Spirit;"
1 Corinthians 12:9 "To another
(3)faith by
the same Spirit; to another
(4)the gifts of healing by
the same Spirit;"
1 Corinthians 12:10 "To another
(5) the working of miracles; to another
(6) prophecy; to another
(7)discerning of spirits; to another
(8)divers kinds of tongues; to another
(9)the interpretation of tongues:"
1 Corinthians 12:11 "But all these worketh that one and
the selfsame Spirit, dividing to every man severally as he will."
In reality there are nine. Now I am willing to merge diverse tongues and interpretation of tongues even though there really is a difference. As for knowledge and wisdom? Two entirely different things.However, the main point is "echad" or "oneness" out of plurality. I think you have made that well.
