I think this is a legitimate expression of his desire to not live in splendor and grandeur.
Matthew 8:19-20
Then a scribe came and said to Him, “Teacher, I will follow You wherever You go.” Jesus said to him, “The foxes have holes and the birds of the air have nests, but the Son of Man has nowhere to lay His head.”
Personally, I think one of the greatest tragedies of the modern American (Western?) Church is our rampant, unbridled materialism and refusal to share generously with those in need. I am NOT talking about forced redistribution by a cold-hearted, corrupt government agency, but a voluntary LOVING gesture and a spirit of true sacrifice. I applaud Pope Francis for his example
Amen!
