We do not use the terms "christian" or "Christ." We use Messianic and Messiah.
While the Hebrew Mashiach and the Greek Christos are similar in meaning - anointed one - they differ in degree. Christos is anointed by dabbing a drop of oil on the forehead. Mashiach is anointed by pouring oil over the head so it drips off the clothes.
Psalm 133:2
It is like the precious oil upon the head,
Coming down upon the beard,
Even Aaron’s beard,
Coming down upon the edge of his robes.
What is your reference for this, beyond a quote from Psalm 133?
FYI, here is the Psalm in its entirety...
Look! How good and how pleasant it is
when brothers truly live in unity.
It is like fine oil poured on the head,
which flows down the beard—
Aaron’s beard,
and then flows down his garments.
It is like the dew of Hermon,
which flows down upon the hills of Zion.
Indeed, that is where the Lord has decreed
a blessing will be available—eternal life.
Also, Psalm 45:7, "You love justice and hate evil. For this reason God, your God, has anointed you with the
oil of joy, elevating you above your companions."
and Mark 14:3-7, "Now while Jesus was in Bethany at the house of Simon the leper, reclining at the table, a woman came with an alabaster jar of costly aromatic oil from pure nard. After breaking open the jar, she poured it on his head. But some who were present indignantly said to one another, “Why this waste of expensive ointment? It could have been sold for more than 300 silver coins and the money given to the poor!” So they spoke angrily to her. But Jesus said, “Leave her alone. Why are you bothering her? She has done a good service for me. For you will always have the poor with you, and you can do good for them whenever you want. But you will not always have me! She did what she could.
She anointed my body beforehand for burial. I tell you the truth, wherever the gospel is proclaimed in the whole world, what she has done will also be told in memory of her.”
So clearly, your statement that
Christos is anointed by dabbing a drop of oil on the forehead is not scriptural.
