and he that watereth are one." 12:13--"All baptized into one body."
John 17:22, 23--"That they may be one, even as we are one ... that
they may be made perfect in one."

The word "one" in these scriptures is used in a collective sense;
the unity here spoken of is a compound one, like unto that used in
such expressions as "a cluster of grapes," or "all the people rose
as one man." The unity of the Godhead is not simple but compound.
The Hebrew word for "one" (yacheed) in the absolute sense, and which
is used in such expressions as "the only one," is _never_ used
to express the unity of the Godhead. On the contrary, the Hebrew
word "echad," meaning "one" in the sense of a compound unity,
as seen in the above quoted scriptures, is the one used always to
describe the divine unity.

(2) The Divine Name "God" is a plural word; plural pronouns are
used of God.

The Hebrew word for God (Elohim) is used most frequently in the
plural form. God often uses plural pronouns in speaking of Himself,
e. g., Gen. 1:26--"Let _us_ make man." Isa. 6:8-"Who will go for
_us_?" Gen. 3:22--Behold, man is become as "one of _us_."

Some would say that the "us" in Gen. 1:26--"Let us make man," refers
to God's consultation with the angels with whom He takes counsel
before He does anything of importance; but Isa. 40:14--"But of
whom took he counsel," shows that such is not the case; and Gen.
1:27 contradicts this idea, for it repeats the statement "in the
image of God," not in the image of angels; also that "GOD created
man in HIS OWN image, in the image of God (not angels) created he
