When Jesus was teaching in the Sermon on the
Mount, was he merely explaining the Law to bring the Jews into
closer alignment with God’s will, or was he setting forth principles
that would operate in the coming kingdom? It is understood that
there was already a kingdom operating, from the meaning of the word
(reign, rule) and from various passages indicating its presence
under the Mosaic arrangement. It must also be understood that the
kingdom of Christ was still future, on the basis of various Old
Testament prophecies and from Jesus’ own predictions.
A Preliminary Consideration
Jesus’ promise of the Spirit’s coming to his
apostles to remind them of his teachings and to guide them into all
truth (Jn. 14:26; 16:13) is crucial to a proper understanding
of this matter. The Spirit’s work would enable the apostles to
teach the word of Christ; if Jesus taught only to clarify the Law of
Moses and the prophets, then he needed not to remind the apostles,
who would teach people living in the time of the new covenant of
Jesus’ teaching and work. The Holy Spirit, however, saw fit to
reveal such matters for the benefit of all who would live after
Pentecost, and I have to conclude there was something of value,
something pertinent or relevant to our welfare under the new
arrangement of the new covenant of Jesus Christ. Mathew, Mark,
Luke, and John wrote their inspired records after the church began,
so they could not have written for the benefit of the people still
under the Law. In fact, none after the beginning of the church
needed such information from the life of Jesus, if its sole purpose
was to point the Jews to a proper keeping of the Law until the cross
of Jesus.
It is sometimes replied that what Jesus said
while on earth must be repeated in the Law that went forth beginning
on Pentecost at the church’s beginning, in order for it to be part
of the new covenant. Such a contention is sometimes based on the
need for such matters to be “confirmed… by them that heard him”
(Heb. 2:3). Misunderstanding the meaning of “confirmed” is the
problem here. It does not mean that earlier teaching must be
repeated by the apostles after Pentecost, but that what Jesus did
and taught was made firm, established, or guaranteed by the Holy
Spirit’s work in the apostles of Christ through their signs,
wonders, and miracles (Heb. 2:4). Jesus spoke of this “great
salvation” while on earth; in fact he began the speaking of it,
arranging for others later to confirm it. A crucial question is then
raised: If Jesus merely clarified and explained the Law of Moses,
where was there room for him to speak of the “great salvation” which
he had brought to the world? Another crucial question must also
arise: If Jesus’ teaching related only to the Law, then why did the
Spirit after Pentecost need to remind the apostles of his earlier
teaching, for them to proclaim and record such for all to know?
The Role of the Law
What
role did the Law of Moses play, and what was Jesus’ relation to
it? The answer to these questions is also crucial in understanding
these matters. We can know that Jesus did not come to earth to
destroy the law or the prophets, but to fulfill/complete (Mt.
5:17-18). We can learn that he did not abrogate the law before
its time appointed by God at the cross (Col. 2:14; Eph. 2:14);
nor did he disregard its instructions or implications for him, as
evidenced by his obedience and his attitude described in our text
and seen during the totality of his ministry. He constantly observed
its instructions, participated in its ceremonies, and enjoined its
obligations on others in far too many instances to need to cite
here. He lived and died under the operation of Moses’ Law (Gal.
4:4; 3:19-25). Only when Jesus had lived, died, arisen, and
ascended could the gospel system/new covenant/law of Christ go forth
from Jerusalem as the prophets had predicted (Isa. 2:4; Lk.
24:46-47).
In view of his proper regard for the law and the
prophets, why did he insert such a section at this point in his
Sermon on the Mount? Against the backdrop of our teaching of the
end of the Law and the beginning of his way from Pentecost onward,
Jesus must have been thwarting any misunderstanding of his view of
the Law and his relation to it. He did not want any to think that
he encouraged disregard for God’s law by statement or example,
because his focus was to prepare material for the coming kingdom. Just as King David gathered materials in preparation for the temple
that Solomon would build, so Jesus and John before him prepared the
spiritual material for the church by the teaching which they did. In the Sermon on the Mount Jesus set forth primary principles to
guide the thinking and conduct of kingdom citizens, though the
kingdom was still future. While it is true that the basic moral
principles that he taught were not appreciably different from those
of the Law and prophets (Mt. 7:12; 22:40), it is also correct to say
that he extended them and applied them in ways that they had never
been understood before. In the series of contrasts found in
Matthew 5:21-48, he certainly dealt with their misunderstanding of
the Law and, possibly, with Pharisaic teaching (as in 5:43). It
is highly unlikely that he was here placing himself in opposition to
the Law itself, immediately after upholding the Law and the
prophets. It is also significant that the Son of God, the
soon-to-be king of the new kingdom, asserted his own authority in
his repeated pronouncements (“but I say unto you”). Little wonder
that the people saw a profound difference between his authoritative
teaching and that of the scribes. He took the foundation laid for
such matters in the Law and then built on that foundation kingdom
law; what began as an early bud under the Law later blossomed under
Christ’s gospel. It also should be remembered that Jesus’
teaching about love, begun here in this sermon, he later summarized
and applied to his disciples’ love for each other, calling his
teaching “a new commandment” (Jn. 13:34).
It was new (kainos) in quality, form, or
nature, not in time. Let there never arise any doubt that Jesus
prepared people for the coming kingdom in his own ministry, even
while he obeyed the Law of Moses and urged them to do the same. He
was seeking a holy people, even as Israel could have been such under
the Law. The purpose of his ministry was preparatory, while he
personally also looked backward to the Law under which he lived. To be faithful to God, who had sent him to prepare for the future,
he could not do otherwise.
Other Preparations for the Kingdom
In the Sermon on the Mount, Jesus prepared people
for the kingdom. To exclude this element of his ministry is to
strip him of any reason for coming to earth in the flesh. The
prophets had explained the Law, clarified its spiritual impact on
the lives of Israelites, and urged their obedience thereto from the
heart. Jesus was not just another in the long line of Old
Testament prophets, though he was a divine prophet (Heb. 1:1-4). He was God’s final prophet who must be heard. Even during his
life, God spoke from heaven to certify him as the one to be heard,
in contrast to Moses and Elijah, whose time was either past or
passing (Mt. 17:5). He had to be heard even then, for he had
something to say that the Law and the prophets did not fully say.
At a time when the Jews little understood the spiritual nature of
the coming kingdom, his teaching provided a needed element as he
staked out the very spiritual boundaries for all to know. Though
he did not give all details concerning the church, he did clarify
its spiritual nature and character.
Jesus also gave some specific teaching that would
operate in the new kingdom/church, in addition to that found in the
Sermon on the Mount. He taught how to solve the problem of
personal offenses in Matthew 18:15-17. He also gave to his
apostles their places of authority in his teaching in Matthew
16:18-19; 18:18-20; 19:28. Jesus taught concerning true
worshippers and their worship for the time of the church in John
4:22-24. He instituted the Lord’s supper in Matthew 26 and
parallel accounts and indicated its “new” (form of kainos,
earlier defined) place when “the kingdom of God shall come” (Lk,
22:18). Jesus gave the account of the woman anointing him at
Simon’s house in Bethany a deserved place in the preaching of the
gospel in Matthew 26:6-13. Jesus also gave the apostles their
marching orders for their post-Pentecost work and, in doing so, also
laid down the path into the new kingdom (Mt. 28:19-20; Mk. 16:15-16;
Lk. 24:46-47). In reality he had already dealt with the
fundamental principles of obedience or submission to him in the
Sermon on the Mount, defining them as the way to enter the kingdom
(Mt. 5:20; 7:13-27).
He had also taught about the new birth in John 3
as a means of entering the kingdom, just as he did conversion in
Matthew 18:3. He had something to say about the significance of
his blood before it was shed in John 6:55. The many
kingdom parables taught by Jesus say much concerning the coming
kingdom, not the kingdom of Old Testament Israel; we believe such to
true because Jesus would not have tried to conceal the mysteries of
that kingdom at such a late time, when its very survival was in
jeopardy, especially in view of his effort to “clarify the law of
Moses, as some claim he was doing (clarifying and concealing do not
fit together). To deny that Jesus could teach concerning the church
during his personal ministry is to assert something without Biblical
proof. The proof shows that he did so; to assert otherwise is to
state a theory requiring more proof than has been given.
A Similar Situation
Did not Moses reveal to Israel in Egypt the
Passover observance, at least in its elementary stage, and yet later
actually reveal its fullness in the Law for continuing
observance? Do we not have a similar situation in his revealing
the Sabbath regulation as a test of their willingness to obey God in
Exodus 16, though it was not revealed for their perpetual observance
until Mount Sinai (Neh. 9:13-14)? It ought to be obvious that
while one arrangement (the Patriarchal) was in force, God set forth
something that was coming under the next arrangement (Mosaic
Covenant). If such could happen then, why could it not also
happen during Jesus’ ministry, as he kept the Law and urged others
to do likewise, that he made preparation for the next economy (His
own) by preparing spiritual material in the people willing to
listen? To concede that such happened earlier in Bible history,
as we have pointed out, is to admit the possibility of such taking
place again when Jesus was present on earth. It was no more
impossible then than it had been earlier! If one wishes to call
this kind of situation a merging of two covenants, as if such could
never happen, he may do so; but he has misnamed it, for the one who
planned all covenants/economies has the right to provide such
previews/prophecies as he deems best. Who is man to counsel
God? He has the right to test man’s faith in whatever way he
chooses, or to preview his coming economy as he sees fit.
