John 10:30 I and my Father are one.

Greek : 

Literal Verse: 

The Father and I are united. >

KJV : 

Jhn 10:30 I and my Father are one.

Interesting and Hidden Aspects: 

This verse is, of course, used as evidence that Christ taught the idea of the Trinity. This is not an argument against the Trinity, but simply an observation of how Christ uses the word "one" and what it means.

Christ uses this statement of "being one"in key ways (see related verses) to describe unity and togetherness generally.

Christ uses it to refer to his followers being united (Jhn 17:11). He specifically says that he wants his followers to emulating the togetherness of Christ and his Father. If this idea only applied to the unity of the Trinity, asking his Father that his followers could be one as Christ and the Father are one, would not make any sense unless all Christ's followers are also part of the Trinity or their own union like the Trinity.

More explanation is offered in Jhn 17:21 where Christ describes what he means. The KJV translated this verse as:

Jhn 17:21 That they all may be one; as thou, Father, art in me, and I in thee, that they also may be one in us: that the world may believe that thou hast sent me.

But, out alternatative translation is:

That all these might be united, even as you, Father with me and I with you; that they may also be with us; that the world order might believe you sent me out for this.

You can see how the term "united" works here. However, the translation of the Greek "en" as "with" might be a little misleading. The unity Christ describes is "internal" that is, "within", as in a unity of spirit and mind rather than external. This is a joining of purpose, vision, and knowledge.
