What’s the oldest living book or letter of the new testament? I just want something to prove to Muslims that the oldest written document of Christianity pointed to Christ as God.
Check out this website of the earliest documents and manuscripts:

Also, here are some writings of the early Church Fathers.
**St. Ignatius of Antioch, Letter to the Romans Address (c. 110 AD) **
“Ignatius, also called Theophorus, to the Church that has found mercy in
the greatness of the Most High Father and in Jesus Christ, His only Son: to
the Church beloved and enlightened after the love of Jesus Christ, our God,
by the will of Him that has willed everything which is: to the Church also
which holds the presidency in the place of the country of the Romans … To
those who are united in flesh and in spirit by every commandment of His,
who are filled with the grace of God without wavering, and who are filtered
clear of every foreign stain, I wish an unalloyed joy in Jesus Christ, our
God.”
**St. Melito of Sardes, Fragment in Anastasius of Sinai 13 (c. 177 AD) **
“The activities of Christ after His Baptism, and especially His miracles,
gave indication and assurance to the world of the Deity hidden in His flesh.
Being God and likewise perfect man, He gave positive indications of His
two natures: of His Deity, by the miracles during the three years following
after His Baptism; of His humanity, in the thirty years which came before
His Baptism, during which, by reason of His condition according to the
flesh, he concealed the signs of His Deity, although He was the true God
existing before the ages.”
St. Irenaeus of Lyons, Against Heresies 3, 19, 1 (c. 180 AD)
“Nevertheless, what cannot be said of anyone else who ever lived, that He
is Himself in His own right God and Lord and Eternal King and Only-
begotten and Incarnate Word, proclaimed as such by all the Prophets and
by the Apostles and by the Spirit Himself, may be seen by all who have
attained to even a small portion of the truth. The Scriptures would not have
borne witness to these things concerning Him, if, like everyone else, He
were mere man. But that He had in Himself what no other ever had, that
pre-eminent generation by the Most High Father; and that He also
experienced that pre-eminent birth from a Virgin,––the divine Scriptures
testify to both in His regard.”
Clement of Alexandria, Exhortation to the Greeks 1, 7, 1 (ante 200
AD)
“This Word, then, the Christ, the cause of both our being at first (for He
was in God) and of our well-being, this very Word has now appeared as
man, He alone being both, both God and man—the Author of all blessings
to us; by whom we, being taught to live well, are sent on our way to life
eternal. For, according to that inspired apostle of the Lord, the grace of God
which brings salvation has appeared to all men, teaching us, that, denying
ungodliness and worldly lusts, we should live soberly, righteously, and
godly, in this present world; looking for the blessed hope, and appearing of
the glory of the great God and our Savior Jesus Christ.”
