Our Messiah is the firstborn of all creation, as well as the firstborn of the dead, as well as being the firstborn of Mary and Joseph.
Can an unclean things bring forth a unclean thing? Once there was this tomb outside of Jerusalem that did.
For those whom he foreknew he also predestined to be conformed to the image of his Son, in order that he might be the first-born among many brethren. Rom. 8:29
Aside from being the great “predestination” verse we are also informed the Messiah is the firstborn of the brethren. He is the pre-eminent leader of His Congregation. The firstborn were to be dedicated to God, they were the head of the family and as such were responsible for the others welfare. No one can or should try to usurp His firstborn status. He is our leader. We have no king but Messiah.
He is the image of the invisible God, the first-born of all creation; Col. 1:15
This is not to mean as some cult teach that Messiah is a creation. The Greek is actually prototokos pases ktiseos which is, born before all the creation. The word, with only the change of the accent, prototokos, signifies actively the first begetter or producer of all things. The firstborn here is used in the sense of His pre-eminence.
He is the head of the body, the church; he is the beginning, the first-born from the dead, that in everything he might be pre-eminent. Col. 1:18
He is the head of the Congregation as ancient kings were heads of the kingdoms. He is the head of the government with the right to make and enforce laws. The Greek is arche, prototokos ek o nekros, beginning, ruler, principle, born or the dead.
