It’s really not a “creative” interpretation, D-fendr. This is from my ESV Study Bible:
“Peter is given the authority to admit entrance into the kingdom through preaching the gospel, an authority that is subsequently granted to all who are called to proclaim the gospel. (Note the contrast with the scribes and Pharisees, who shut the kingdom in people’s faces, neither entering themselves nor allowing others to enter). In Acts, Peter is the apostle who first preaches the message of the kingdom to the Jews at Pentecost, to the Samaritans, and to the Gentiles.”
Again, my perspective is not unique or creative, but consistent with what many scholars hold, including those who contributed to the ESV Study Bible.
At the risk of sounding too Protestant: I’ll take Jesus’ plain meaning over the doctrines of ESV (men).
