I read the article... thanks Kayla for posting the link.
I could agree with the article, if I could attach a long list of caveats, restrictions and further explanations. The problem I would have with it is not in what they are actually saying (the overall message, not the details) but in the implications of it. It's like a ship heading in the general direction of its intended destination. If they hold to course without correcting, they won't end up where they thought they were going. A couple of degrees off is still off.
I understand what the writer is saying about idolatry, and I have certainly seen that kind of belief on this forum, but I think he's blowing the whistle on it way too early. If we do not allow the words of the Bible to have enough place in our lives that they can "judge the thoughts and intentions of our hearts" (Hebrews 4:12), can we rightly conclude that we are following Jesus? We don't worship the letter, but we take it very seriously as God's words to us, and grow in Him as we read, interpret, and apply the word.
So, can a person be a Christian and not believe the Bible? Technically, yes, just as a newborn human is fully human without yet eating or drinking. A Christian won't grow much if they don't feed on the word. Even those who prefer to relate with Jesus primarily through prayer and worship rather than Scripture will be directed to Scripture by the Holy Spirit, for He will teach what is consistent with Scripture. Most of what we know about God, we know by Scripture. Neglecting, avoiding or rejecting what He has "written" about Himself and about how we are to relate to Him is silly.
