Actually in Biblical symbolism
The left is the side of the flesh … as in the goats on the left side of Christ.
The right is the spirit … as in the sheep being on the right side.
The cross does not signify the Trinity, but the four voices of God as he speaks through priests, prophets, judges and kings.
Christians from the second century on have only read the Bible in the voice of the king (Literal-historical events in common language).
The voice of the priest speaks of the Eternal Son in a heavenly language. The Prophet speaks of Jesus in a heavenly language. The judge speaks God's judgement on the liter-historical events.
All four speak simultaneously through the same words in scripture.
The death of Christ's on the cross was in accordance with the full revelation of God's word.
Why would you believe this over any other proposition? Let's play a game:
Read Acts 12 Think mirror:
Who vexed the church? When did he vex Christ?
When was Peter arrested? and Jesus?
When was Peter to be brought out of prison? When did Jesus get out of the tomb?
Put between 2 what? guards, thieves?
Where did the light shine? cell, tomb?
Who was poked in the side? Peter, Jesus?
Why 2 sets of guards and a gate?
Why 2 days in death and a stone?
What did the gate and stone do?
Who did Jesus first see in resurrection, where did Peter go?
Who ran to tell the disciples?
Who was told she was crazy?
Now that you see the mirror, find a theologian since the first century who shows it to you, and you will find someone who knows how to read the Bible properly.
All of the literal-historical accounts speak of Christ in this way. How else would God, whom no man has or can see or hear, reveal himself as being involved with all of history except to embed hidden pictures of him being involved in all history?
The story told is not what you have been told.
