Actually, it's only Jesus and John the Baptist that are being talked about.

I don't have to know Greek to understand it. People who know Greek much better than you translated it for me.

The Bible clearly teaches the Trinity over many passages. Here are some:

(John 14:8-10 NIV) Philip said, "Lord, show us the Father and that will be enough for us." {9} Jesus answered: "Don't you know me, Philip, even after I have been among you such a long time? Anyone who has seen me has seen the Father. How can you say, 'Show us the Father'? {10} Don't you believe that I am in the Father, and that the Father is in me? The words I say to you are not just my own. Rather, it is the Father, living in me, who is doing his work.

(Acts 15:28-29 NIV) It seemed good to the Holy Spirit and to us not to burden you with anything beyond the following requirements: {29} You are to abstain from food sacrificed to idols, from blood, from the meat of strangled animals and from sexual immorality. You will do well to avoid these things. Farewell.

(Acts 13:2 NIV) While they were worshiping the Lord and fasting, the Holy Spirit said, "Set apart for me Barnabas and Saul for the work to which I have called them."

(Matthew 28:18-20 NIV) Then Jesus came to them and said, "All authority in heaven and on earth has been given to me. {19} Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, {20} and teaching them to obey everything I have commanded you. And surely I am with you always, to the very end of the age."

(Isaiah 9:6-7 NIV) For to us a child is born, to us a son is given, and the government will be on his shoulders. And he will be called Wonderful Counselor, Mighty God, Everlasting Father, Prince of Peace. {7} Of the increase of his government and peace there will be no end. He will reign on David's throne and over his kingdom, establishing and upholding it with justice and righteousness from that time on and forever. The zeal of the LORD Almighty will accomplish this.

(Psalms 72:5-8 NIV) He will endure as long as the sun, as long as the moon, through all generations. {6} He will be like rain falling on a mown field, like showers watering the earth. {7} In his days the righteous will flourish; prosperity will abound till the moon is no more. {8} He will rule from sea to sea and from the River to the ends of the earth.
