With Respect to Him Being the Savior and the Redeemer
This proof involves four main points:
A. God alone redeems and saves the human
race
B. The theological basis of this fact
C. Christ alone is the Redeemer and Savior of
the world
D. Conclusion: Christ is God.
(A) God Alone Redeems and Saves the Human Race
The Holy Bible explicitly testifies to this. It is written in the
Book of Psalms: "None of them can by any means
redeem his brother, nor give to God a ransom for him...
But God will redeem my soul from the power of the grave"
(Ps. 49:7,15). David the Prophet repeats the same
meaning when he says: "Bless the Lord, O my soul, bless
His holy name! ... who forgives all your iniquities... who
redeems your life from destruction" (Ps. 103:1-4). And the
Book of Isaiah the Prophet confirms this matter in more
than one testimony. It is written: "Thus says the Lord, the
King of Israel, and his Redeemer, the Lord of hosts: 'I am
the First and I am the Last; besides Me there is no God "
(Is. 44:6). Therefore the Redeemer is This One God who
is the Lord of hosts who is the First and the
Last. Isaiah the Prophet repeats the same thing and says:
"As for our Redeemer, the Lord of hosts is His name, the
Holy One of Israel" (Is. 47:4) and: "Thus says the Lord,
your Redeemer, the Holy One of Israel 'I am the Lord
your God"' (Is. 48:17). And God says: "For I, the Lord
your God, will hold your right hand..' says the LORD and
your Redeemer, the Holy One of Israel" (Is. 41:13,14).
The Virgin Mary attributed salvation to God and said: "My
soul magnifies the Lord, and my spirit has rejoiced in God
my Savior" (Lk. 1:46). St. Paul the Apostle said: "God our
Savior" (Titus 2: 10), and: "The kindness and the love of
God our Savior toward man appeared' (Titus 3:4). And
Jude the Apostle concludes his Epistle with the same
testimony, saying: "Now to Him who is able to keep you
from stumbling and to present you faultless before the
presence of His glory with exceeding joy, to God our
Savior who alone is wise, be glory and majesty, dominion
and power, both now and forever. Amen" (Jude 24,25).
Salvation is attributed to God alone, as is explicitly stated
by God Himself. "And you shall know no God but Me, for
there is no Savior besides me" (Hos. 13:4); "Have not I,
the Lord? And there is no other God besides Me, a just
God and a Savior, there is none besides Me" (Is. 45:2 1),
and: "I, the Lord, am your Savior, and your Redeemer,
the Mighty One of Jacob" (Is. 49:26); (Is. 60:16).
(B) The Theological Basis of this Fact
(1) The sin in which the first man fell and in which every
man falls is a sin against God because it is disobedience
to God, and lack of love and respect towards Him. But
rather it is rebellion against His kingdom and resistance to
the work of His grace and His Holy Spirit, as well as being
a lack of faith. That is why David the Prophet says in his
Psalm: "Against You, You only, have I sinned, and done
this evil in Your sight" (Ps. 51:4). That is why the
righteous Joseph withheld from sinning, saying: "How
then can I do this great wickedness, and sin against
God?" (Gen. 39:9)
(2) All human beings sinned: "They have all turned aside,
they have together become corrupt, there is none who
does good, no, not one" (Ps. 14:3). The wages of sin is
death (Rom. 6:23), and "thus death spread to all men,
because all sinned' (Rom. 5:12).
(3) Because sin is against God and since God is infinite,
then sin is infinite and its punishment is infinite. Should it
be redeemed, it must be by an infinite atonement,
sufficient for the forgiveness of all the people of all
generations to the end of the ages.
(4) Only God is Infinite. Therefore He Himself had to take
flesh and become the Son of Man in order to replace man
and "to be the propitiation for the whole world' (1 Jn. 2:2).
(5) This propitiation was effected by the Lord Jesus Christ
to save the whole world. If He were not God, His
propitiation would be utterly invalid because His
propitiation derived its infinity from Him being Infinite
God, of whom the Apostle said: "In Him dwells all the
fullness of the Godhead bodily" (Col. 2:9).
(C) Christ Is the Only Savior and Redeemer of the
World
At the Annunciation, the angel said that Christ the Lord
would be called Jesus, "for He will save His people from
their sins" (Matt. 1:2 1). Yet His salvation was not for His
own people only, for He said: "I did not come to judge the
world but to save the world' (Jn. 12:47). And it was said of
Him: "This is indeed the Christ, the Savior of the world'
(Jn. 4:42). And He said of Himself that He "has come to
save that which was lost" (Matt. 18:11), and the whole
world was under the penalty of death.
Christ came to save mankind from sins. It is written that
"He will save His people from their sins" (Matt. 1:21). St.
Paul the Apostle said: "Christ Jesus came into the world
to save sinners, of whom I am chief" (I Tim. 1: 15), that
He "gave Himself for us, that He might redeem us from
every lawless deed" (Titus 2:14), and that He "has
redeemed us from the curse of the law" (Gal. 3:13).
Christ offered a complete and everlasting salvation.
St. Paul the Apostle said that Christ, the High Priest, "is
also able to save to the uttermost" (Heb. 7:25) and that
"He became the Author of eternal salvation to all who
obey Him" (Heb. 5:9). That is why the Apostle wondered,
saying: "How shall we escape if we neglect so great a
salvation!" (Heb. 2:3)
Therefore, to sum up, Christ came a Redeemer and a
Savior and a Propitiator to save all the people of the world
from their sins, and to redeem them from all their
iniquities and from the curse of the Law. He offered an
everlasting salvation to the uttermost.
Christ Alone Is the Savior
St. Peter the Apostle said: "For there is no other name
under heaven given among men by which we must be
saved' (Acts 4:12).
(D) Conclusion: Christ Is God
(i) As we mentioned before, the salvation of the world
from sins needed an infinite propitiation and none is
Infinite except God alone. Since the Lord Jesus Christ
offered the propitiation and completed it to the uttermost
and redeemed all the people from every iniquity, saving
them eternally from the curse of the Law, therefore, He is
Infinite and thence He is God.
The act of redemption is an excellent proof confirming
that Christ is God because if He were not so, the
redemption would not have been considered valid and
would not have been sufficient for the salvation of the
whole world from all their sins.
(ii) God says: "'You shall know no God but Me; for there
is no Savior besides Me" (Hos. 13:4), and: "there is no
other God besides Me, a just God and a Savior, there is
none besides Me" (Is. 45:21). And it has been proved that
there is a Savior who is Christ Jesus who is the only
Savior and that there is no other name under heaven
given among men by which we must be saved (Acts
4:12). How can we make all these verses conform with
each other? Is, God not true or is the Holy Bible not true?
Far from it. Let God be true. God cannot be true unless
God is Christ so that if we say that God is the Savior, we
mean at the same time that Christ is the Savior.
(iii) If Christ were not God, and having sacrificed Himself
for the sake of all people because of His love for them,
does He love people more than God does? Is there any
being who surpasses God in His love to mankind? Not
even Jehovah's Witnesses can say such a thing.
(iv) If Christ were other than God, and He was compelled
to complete the work of redemption for the mere
obedience of a command, then redemption would have
lost its most important principle, and in addition, it would
contradict the words of the Lord Jesus Christ: "Greater
love has no one than this, than to lay down one's life for
his friends" (Jn. 15:13). And this also would disagree with
the Holy Bible which says that Christ "gave Himself up for
us, that He might redeem us from every lawless deed'
(Titus 2:14).
(v) If Christ were other than God, and God commissioned
Him to undertake this deed because of God's love to the
world according to the verse: "For God so loved the world
that He gave His Only Begotten Son" (Jn. 3:16), does this
mean that God loved the world at the expense of
Another? No, never! This verse cannot be
properly understood unless God and Christ are One, as
the Lord Jesus said: "I and My Father are One" (Jn.
10:30). Thus we understand that God redeemed the
people Himself, accomplishing the words of the Holy
Book: "None of them can by any means redeem his
brother, nor give to God a ransom for him... But God will
redeem my soul from the power of the grave" (Ps.
49:7,15). Then the words of St. Paul the Apostle:
"because we trust in the living God, who is the Savior Of
all men" (1 Tim. 4:10), will be true.
(vi) If Christ were other than God, then people would not
be wrong when they worship Him and not God, because
He created them from nothing, according to the Bible's
words: "All things were made through Him and without
Him nothing was made that was made" (Jn. 1:3,10).
Jehovah's Witnesses profess that Christ is the Creator
and that He bought them with His precious Blood, and
purified them for Himself as His own special people (1
Pet. 1: 8); (Titus 2:14). Who can blame a nation who
worship their own Creator and Savior?
(vii) We adhere to the belief that Christ is God, not only
because it is the fundamental proof of completing the
work of redemption, but also because it is an affirmation
of God's words: "I will ransom them from the power of the
grave, I will redeem them from death" (Hos. 13:14). God
attributed to Himself this deed which He carried out. So
let God be true. And let Christ's words. "I and My
Father are One" (Jn. 10: 30), be true.
