verse 15 - He asks them.
verse 16 - Simon answers "You are..."
verse 17 - Jesus says "Simon you are blessed. Flesh and blood did not reveal this to you, but my father in heaven"
verse 18 - Jesus says "you are rock and on this rock, I will build My Church'
verse 19 - Jesus says "I will give you the keys of heaven...
verse 20 - Then He charged his disciples that..In Latin this is clearly in verse 15 he asks them (vos), in verse 17 he uses second person singular (es), the same in verse 18 (tu es ) and verse 19 (tibi ). But in verse 20 he uses plural third person (ut)
Going by the grammar, in verses 15 and 20 these are addressed to plural second or third persons (vos and ut respectively) while in 17, 18 and 19 this is 2nd person - tu es and tibi
15 - Who do you'all :) say I am
17 - you (singular) are blessed
18 - I say to you (sing) that you (sing) are rock
19 - I will give unto thee (sing)
20 - He commanded them (plural)
Though, good catch on dative for "commanded THEM" :)
Now THIS is a darned good question!
I'm glad you asked it!
