Tertullian

“ Look to it then, that it be not you rather who are destroying the Monarchy, when you overthrow the arrangement and dispensation of it, which has been constituted in just as many names as it has pleased God to employ. But it remains so firm and stable in its own state, notwithstanding the introduction into it of the Trinity, that the Son actually has to restore it entire to the Father; even as the apostle says in his epistle, concerning the very end of all: “When He shall have delivered up the kingdom to God, even the Father; for He must reign till He hath put all enemies under His feet;” ”

“ No one, therefore, will impair it, on account of admitting the Son (to it) , since it is certain that it has been committed to Him by the Father, and by and by has to be again delivered up by Him to the Father. ”
