To MARK OUT BEFOREHAND — pro ('before') + horizō ('to set a boundary'), the same verb behind 'horizon' and behind Romans 1:4's 'appointed Son of God'. The Latin praedestinare gave English PREDESTINE, which now arrives carrying five centuries of argument the Greek word did not originally have (Augustine against Pelagius, Calvin against Arminius). ⚠ Worth noticing WHAT Ephesians 1 says is predestined: not who is damned, but that those in Christ are destined FOR ADOPTION and TO BE HOLY. The chapter states a purpose, not a roster. This translation reads 'marked out beforehand' so the boundary-drawing image can be heard before the systems reach it. Romans 8:29 is the verse the whole argument is fought over, and it is worth being exact about what it says: they are marked out beforehand TO BE FORMED WITH THE IMAGE OF HIS SON — a marked-out destination. Whether the marking also fixes WHO travels to it is the Calvinist-Arminian question, and the verse leaves it to inference in both directions. KJV and RV import the Latin 'predestinate'; ASV and NWT retreat to 'foreordained'. → first discussed at Ephesians 1:5
