Then the high priest tore his [g]robes [in mock horror] and exclaimed, “He has blasphemed [by making Himself God’s equal]! What further need have we of witnesses or evidence? See, you have now heard the blasphemy. What do you think?” They answered, “[h]He deserves to be put to death.” – Matthew 26:65-66
Jesus placed Himself by the side of the Father and the Spirit as together with them constituting the one God, as equal in all respects to the Father and the Spirit.
And great, we confess, is the mystery [the hidden truth] of godliness:
He (Jesus Christ) who was revealed in human flesh,
Was justified and vindicated in the Spirit,
Seen by angels,
Preached among the nations,
Believed on in the world,
Taken up in glory. – 1 Timothy 3:16
Peter quotes Joel on the Day of Pentecost and says it is the risen, exalted Christ who has poured out the Holy Spirit. Thus, Peter is identifying Christ as God and as associated with the Father and the Spirit.
