Jesus DID embrace accountability and never exempted The Catholic Church. Scripture affirms accountability for teachers of doctrine. Just a very few of just NT verses on this: 2 Peter 2:1, Titus 2:1, 1 Timothy 6:3, Revelation 2:2, James 3:1, Matthew 13:52, Luke 20:46, Ephesians 4:14. All are before 400 AD.
Whereas Jesus never once used The Catholic Church or Catholic Tradition as normative (or as anything; He never so much as even MENTIONED it - for, by or as anything), He did use Scripture normatively (Sola Scriptura). Here’s just 50 examples of where Jesus uses Scripture normatively (Sola Scriptura), all well before 400 AD (in fact, all before 31 AD): Matt 21:42 Matt 22:29, Matt 26:54, Matt 26:56, Matt 2:5, Matt 4:4l, Matt 4:6, Matt 4:7l, Matt 4:10, Matt 11:10, Matt 21:13, Matt 26:24, Matt 27:37, Mark 12:10, Mark 12:24, Mark 14:49, Mark 15:28, Mark 1:2, Mark 7:6, Mark 9:12, Mark 9:13, Mark 11:17, Mark 14:21, Mark 14:27, Luke 4:21, Luke 24:27, Luke 24:32, Luke 24:45, Luke 2:23, Luke 3:4, Luke 4:4, Luke 4:8, Luke 4:10, Luke 4:17, Luke 7:27, Luke 10:26, Luke 18:31, Luke 19:46, Luke 20:17, Luke 21:22, Luke 22:37, Luke 23:38, Luke 24:44, Luke 24:46, John 2:22, John 5:39, John 7:38, John 7:42, John 10:35, John 13:18, John 17:12, John 19:24, John 19:36, John 19:37, John 20:9, John 2:17, John 6:31, John 6:45, John 8:17, John 10:34, John 12:14, John 12:16, John 15:25, John 19:20, John 20:30, John 20:31, John 21:25. There are more, of course.
Here are just some examples of Apostles using it, too, all before 400 AD. In fact, all before 100 AD: **Acts 1:16, Acts 8:32, Acts 8:35, Acts 17:2, Acts 17:11. Acts 8:24, Acts 18:28, Acts 1:29.

Space doesn’t permit all the OT examples.
NO ONE, including Jesus, OT or NT, needed The Catholic Church to tell them what was or was not Scripture. Read the following: Matthew 21:42, Matthew 22:29, Matthew 26:54, Matthew 26:56, Mark 12:10, Mark 12:24, Mark 14:49, Mark 15:28, Luke 4:21, Luke 24:27, Luke 24:32, Luke 24:45, John 2:22, John 5:39, John 7:38, John 10:35, John 13:18, John 17:12, john 19:24, John 19:36, John 19:37, John 20:9
