'Formally' in the Bible

The Pharisees were watching Jesus closely to see if He would heal him on the Sabbath, so that they might accuse Him [in the Jewish high court].

that God has completely fulfilled this promise to our children by raising up Jesus, as it is also written in the second Psalm, ‘You are My Son; today I have begotten (fathered) You.’

Brethren, even a covenant made by a man--to borrow an illustration from daily life--when once formally sanctioned is not liable to be set aside or added to.

I mean that the Covenant which God had already formally made is not abrogated by the Law which was given four hundred and thirty years later--so as to annul the promise.
