No, it suggests that not everything Jesus did was written down, not that we had incomplete teaching.
On the contrary, it tells us this....
2 Timothy 3:14-17 But as for you, continue in what you have learned and have firmly believed, knowing from whom you learned it and how from childhood you have been acquainted with the sacred writings, which are able to make you wise for salvation through faith in Christ Jesus. All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness, that the man of God may be complete, equipped for every good work.
Show us where anyone in Scripture tells us that it is not complete and that we need other sources to teach us things God neglected to include in the Bible.
Do you really think that He WOULDN'T include everything we needed to know?
Who is talking about we NEED to know? Not me?
Yes, in a way I do. The Bible does not, by itself, teach you everything you need to know about being a spouse or a parent. It does not teach you everything you need to know about HOW to put up with the one person in the group who ruins things for everyone else.
Like “complete” the word “need” has slight differences in meaning for different applications or contexts.
It gets my attention that people mostly tall about prayer as though it were nothing but us telling God stuff. But that may not be all it is. And people respond to Monsignor Pope’s article as though he were saying that one sort of prayer was more likely to be heard than another.
I don’t know what he thinks, but I doubt he thinks that God is hard of hearing.
Tell you what: if you don’t think a book on prayer would help you in any way, don’t read it.
