The Son of God
Christ is often called a Son of Yahweh (or Son of God) and various misinformed sects over the centuries have taken this to mean that Christ was the "only" begotten son of God - despite the common phrase being more adequately rendered as "most-beloved". It is a scriptural truth that Adam was a son of God, and that the children of Israel are referred to as sons and daughters several times throughout scripture.
Even an adversary ostensibly recognized this, though it is also very possible that Matthew had just made a clear amendation while recording his account.
Matthew 4:6 and says to Him: “If You are a Son of Yahweh, throw Yourself down, for it is written that ‘He commanded His messengers concerning You, and by their hands they shall bear You, lest at any time You may strike Your foot against a stone.’”
[A son, not THE son, of Yahweh. For this very same reason it is written, in the opening verses of the gospel of John, that “But as many who received Him, He gave to them the authority which the children of Yahweh are to attain, to those believing in His Name”. We do not know the power we would have, if we would only obey Yahweh our Father – all the things which Christ was able to do, He tells us that we too should be able to do.]
When Christ is referred to as the son of God, it is in reference to the Messianic psalm which refers to the Messiah's kingship and inheritance of the Melchizedek priesthood.
