The Socinian objection: Scripture says God grieved and repented that he had made man (Genesis 6)
Against so plain a truth the objections the Socinians usually raise have no force. One is that Scripture presents God as saddened by human sins and moved to repentance: 'The Lord saw that human wickedness was great on the earth and that every thought of the heart was set on evil all the time, and he repented that he had made man on the earth. Grieved to the heart, he said, I will wipe man, whom I created, from the face of the earth' (Genesis 6).
From this they infer that before human beings plunged into every kind of crime God did not know for certain that their wickedness would be so great. Otherwise, they say, there seems to be no reason for saying that on seeing it he was grieved and repented of having created man. No one repents of what he has done unless some new knowledge comes to him, or something happens to him that he did not expect and had not foreseen.

X. Neque contra tam apertam veritatem ullam vim habent quae objicere solent Sociniani. Quale est, Scripturam Deum inducere propter hominum peccata tristitia affectum, & poenitentia ductum. Videns, inquit illa, Dominus quod multa malitia hominum esset in terra, & cuncta cognitio cordis intenta esset ad malum omni tempore, poenituit eum quod hominem fecisset in terra: Et tactus dolore cordis intrinsecus, Delebo, inquit, hominem quem creavi a facie terrae, Geneseos capite sexto. Unde colligunt Deum, antequam sic homines ruerent in omne scelus, non pro certo novisse tantam eorum fore malitiam; Nam alioqui videtur absque ratione dici, illa visa, dolore tactus, & poenitentia affectus fuisse quod hominem creasset. Neque enim aliquis poenitentia ducitur ob ea quae fecerit, nisi nova quaedam ipsum cognitio subeat, aut contingat quiddam ipsi inexpectatum, & non ante praevisum.
