Athanasius of Alexandria, on Gen 2:16

“And he commanded him, saying: Of every tree of paradise thou shalt eat:”

“Knowing once more how the will of man could sway to either side, in anticipation God secured the grace given them by a command and by the place where he put them. For he brought them into his own garden and gave them a law so that, if they kept the grace and remained good, they might still keep the life in paradise without sorrow or pain or care, besides having the promise of incorruption in heaven. But if they transgressed and turned back and became evil, they might know that they were incurring that corruption in death that was theirs by nature, no longer to live in paradise but cast out of it from that time forth to die and abide in death and corruption.”
