Well, I suppose, if you consider the promise of food, God does feed us. In the eucharist and spiritually. If you think about a cardboard box as being sheltered, and some rags as being clothes, I suppose we could pretty much have those things available to us also.
However, being fed in the sense we are guaranteed a full course meal, or having clean clothing and good shelter just isn’t something that can be promised. I’m sure there are plenty of people in the world that trust in God, but have had to go a day or two without food or shelter, and in some cases clothing.
Also I think it worthwhile to mention that John the Disciple was the author of the book of John. John was an integral part of the formation of what is now the Catholic Church. What the Church is now would not be possible if it weren’t for the work of people like John. Although the term “Catholic” wasn’t used in those times to identify a persons perspective of Christian belief, there were certainly no “protestants”. So when you read the Bible keep in mind many of the authors were in a sense “Catholic”.
Catholics shouldn’t be presumptious, but the Catholic Church has the authority from Christ to define the faith and interpret scripture. Any thing that someone teaches in contradiction is simply wrong. How do you teach that to a protestant? No idea. :shrug:
