Ephesians 1:22 and he put all things in subjection under his feet, and gave him to be head over all things to the church,
Ephesians 1:23 which is his body, the fulness of him that filleth all in all.

in red: There is no word for things in Greek the language that almost all of the New Testament is written. It should be italicized if there at all. Also, I believe "All" includes everything spiritual and physical. Another words the whole pie, not just a slice here or there.

in Green: Church: Which your are taught is a building. To bad the Greek word doesn't agree with this.

G1577
ἐκκλησία
ekklēsia
ek-klay-see'-ah
From a compound of G1537 and a derivative of G2564; a calling out, that is, (concretely) a popular meeting, especially a religious congregation (Jewish synagogue, or Christian community of members on earth or saints in heaven or both): - assembly, church.

G1537
ἐκ, ἐξ
ek ex
ek, ex
A primary preposition denoting origin (the point whence motion or action proceeds), from, out (of place, time or cause; literally or figuratively; direct or remote): - after, among, X are, at betwixt (-yond), by (the means of), exceedingly, (+ abundantly above), for (-th), from (among, forth, up), + grudgingly, + heartily, X heavenly, X hereby, + very highly, in, . . . ly, (because, by reason) of, off (from), on, out among (from, of), over, since, X thenceforth, through, X unto, X vehemently, with (-out). Often used in composition, with the same general import; often of completion.


G2564
καλέω
kaleō
kal-eh'-o
Akin to the base of G2753; to “call” (properly aloud, but used in a variety of applications, directly or otherwise): - bid, call (forth), (whose, whose sur-) name (was [called]).

Not a building but a group of people strange, is it not.


Now let's look at body:

G4983
σῶμα
sōma
so'-mah
From G4982; the body (as a sound whole), used in a very wide application, literally or figuratively: - bodily, body, slave.

Doesn't seem divided at all; kind of a real Wholeness kinda ring to it.
Maybe this helps:

Galatians 5:19 Now the works of the flesh are manifest, which are these: fornication, uncleanness, lasciviousness,
Galatians 5:20 idolatry, sorcery, enmities, strife, jealousies, wraths, factions, divisions, parties,
Galatians 5:21 envyings, drunkenness, revellings, and such like; of which I forewarn you, even as I did forewarn you, that they who practise such things shall not inherit the kingdom of God.

This is in a chapter that defines the way you are to walk in Jesus' foot steps and very specifically. For a different look, All Israel were to do things together as a whole, not a piece or a few, but all. When they were divided, they were attacked from all sides. When they kept Gods commandments as a whole they were Blessed Greatly beyond all Nations.

Mathew 12:25 And knowing their thoughts he said unto them, Every kingdom divided against itself is brought to desolation; and every city or house divided against itself shall not stand:
