Acts 20:28 has a textual issue which leads many bible versions to translate as "he obtaioned with his own blood". So it's not a good verse as proof text Jesus is called God. Below is acceptable. It should be "blood of his own", meaning of course, of his own son.
New Revised Standard Version Acts 20:28
Keep watch over yourselves and over all the flock, of which the Holy Spirit has made you overseers, to shepherd the church of God that he obtained with the blood of his own Son
