Is There a Trinity in John 1?

When Titus and 2 Peter say, our great God and Savior, Jesus Christ, this is not some kind of diminished divinity that they're ascribing to Christ. The word God in that time is just more flexible. It's all compatible with my views. Now, about John 1, again, it's kind of subject changing to the deity of Christ away from the Trinity. You don't get the Trinity, right?
