Systematic theology may generally teach the Trinity doctrine, but does that mean the holy spirit (Holy Spirit) is called God in Scripture?
Edmund Fortman:
"The spirit of Yahweh was often described in personal
terms. The spirit was grieved, guided men, instructed
them, caused them to rest (Ps 143:10; Neh 9:20; Is
63:10, 14). But it seems quite clear that the Jews
never regarded the spirit as a person; nor is there
any solid evidence that any Old Testament writer held
this view. A few scholars today maintain, however,
that even though the spirit is usually presented as an
impersonal divine force, there is an underlying
assumption that the spirit was a conscious agent,
which 'provided a climate in which plurality with the
Godhead was conceivable'" (The Triune God, p. 6).
Acts 5:3-4 is not exactly what I would call an
"explicit" identification of the holy Spirit with God.
Granted, Peter does seemingly parallel the holy spirit
and God in these passages. But, again, we must read
texts in their historical context to avoid
skewing their semantic or pragmatic sense. John B.
Polhill, as he is wont to do, provides a nice
explanation:
"Ultimately, he [Ananias] had lied to God. Not that he
had not betrayed the community. Not that he had not
lied to the Spirit. Rather, to betray the community is
to lie to the Spirit that fills the community, and to
falsify the Spirit of God is an affront to God
himself" (Acts, p. 158).
Notice that Polhill does not say the holy spirit is
being called "God" in Acts 5:3-4.
David Hill adds:
"We may have here [in Acts 5] an illustration of
Luke's understanding of the 'sin against the Spirit'
(Luke 12:10) as speech or action against the
constitutive factor of the Church's life" (
Greek Words
and Hebrew Meanings, p. 258).
Recall that Matthew also calls the spirit, God's
finger. This too would clearly explain why the spirit of
God is so closely identified with God in Acts 5:3-4,
although it is not called QEOS in this account. Karl
Rahner states:
"QEOS [in the NT] is still never used of the Spirit"
(
Theological Investigations, 1:138, 143).
Trinitarian scholar Thomas F. Torrance
supplies this account of the Trinity:
"This does not imply that the New Testament presents
us with explicit teaching about the Holy Trinity, far
less with a ready-made formal doctrine of the Trinity,
but rather that it exhibits a coherent witness to
God's trinitarian self-revelation imprinted upon its
theological content in an implicit conceptual form
evident in a whole complex of implicit references and
indications in the gospels and epistles" (
Christian
Doctrine, p. 49).
