'Only Son' in the Bible

Just as he was near the gate of the town, there was a dead man being carried out; he was the only son of his mother, and she was a widow. A large crowd from the town were with her.

So the Logos became flesh and tarried among us; we have seen his glory ??glory such as an only son enjoys from his father ??seen it to be full of grace and reality.

Nobody has ever seen God, but God has been unfolded by the divine One, the only Son, who lies upon the Father's breast.

For God loved the world so dearly that he gave up his only Son, so that everyone who believes in him may have eternal life, instead of perishing.

He who believes in him is not sentenced; he who will not believe is sentenced already, for having refused to believe in the name of the only Son of God.

It was by faith, when Abraham was put to the test, that he sacrificed Isaac, he was ready to sacrifice his only son, although he had received the promises

This is how the love of God has appeared for us, by God sending his only Son into the world, so that by him we might live.
