Who, is an image of the unseen God, Firstborn of all creation, -

And, he, is the head of the body, the assembly, Who is the beginning, Firstborn from among the dead, in order that, he, might become, in all things, himself, pre-eminent; -

in high festival, - and unto an assembly of firstborn ones, enrolled in the heavens, - and unto God, judge of all, - and unto the spirits of righteous ones made perfect, -

and from - Jesus Christ, - The Faithful Witness, The Firstborn of the Dead, and The Ruler of the Kings of the Earth. Unto him that loveth us, and loosed us out of our sins with his blood, -
