Matthew 16:18-19

AUV(i) 18 And I also tell you, [although] you are Peter [i.e., a stone], it is on this rock [i.e., the truth you have just confessed] that I will build my church and [not even] the gates of the unseen place of departed spirits will win out over it [i.e., all efforts to stamp out the church by killing Christians will fail]. 19 [And] I will give you the keys of the kingdom of heaven [i.e., for opening up the way into it]. And whatever [truth] you [and the other apostles. See 18:18] require [people to believe and practice] here on earth will have already been required of them [by God] in heaven. And whatever [truth] you do not require [of people] on earth, will not be required [by God] in heaven.”
