No, you won’t use anything that might possibly confirm the Catholic view, or so it seems.
Joh 15:16 You have not chosen me: but I have chosen you; and have appointed you, that you should go and should bring forth fruit; and your fruit should remain: that whatsoever you shall ask of the Father in my name, he may give it you.
The Greek for appointed is ‘tithēmi’.
G5087
τίθημι
tithēmi
tith’-ay-mee
A prolonged form of a primary word θέω theō (which is used only as an alternate in certain tenses); to place (in the widest application, literally and figuratively; properly in a passive or horizontal posture, and thus different from G2476, which properly denotes an upright and active position, while G2749 is properly reflexive and utterly prostrate): - + advise, appoint, bow, commit, conceive, give, X kneel down, lay (aside, down, up), make, ordain, purpose, put, set (forth), settle, sink down.
You are merely using semantics to validate your view.
