There is a July 8 sermon from Fr. Pfeiffer up on YouTube.

I'm finally able to hear this in its entirety.

Fr. Pfeiffer has some very unique observations on the loaves and fishes gospel.

I've heard it taught that the 7 loaves were like the 7 sacraments. But here he makes
further distinctions, The 7 loaves signify the gospel, the 7 ages of man's life, the 7
sacraments and the 7 virtues.

He says that Our Lord was not pleased when they collected 12 baskets of fragments,
in the 6th chapter of John, where those who received this miracle came back the
next day and abandoned Jesus when He told them "eat my flesh, drink my blood."
Those who had 12 baskets left over were the 5 thousand who had sat on the grass,
that is, in comfort, and they had not eaten deeply, thus all the fragments. They were
primarily Jews who had come from nearby and were too much connected to their
physical pleasures, signified by the 5 thousand like the 5 senses. These did not
benefit from the food because their physical comfort got in the way, and therefore
they could not accept the truth of the message of the Blessed Sacrament.

For the comfort of man interferes with his acceptance of the gospel. I have a
friend who needs this teaching, but I am sad to say, he is not willing to accept it.
He complains about how difficult it is to get to Mass, and how uncomfortable it is
to kneel during low Mass. He longs to make an SSPX retreat, but when you go to
one you are not entertained. It's not a "vacation." You're not going there for food
and relaxation. It's not a resort. We live in an age so remote from the Faith, that
trying to tell someone about an Ignatian retreat is like trying to describe moral
theology to a cannibal. These 5 thousand left Jesus Christ because they thought
he was a cannibal.

But the 4 thousand came from afar, so they were hungry. And they ate sufficiently
because of their hunger. The 4 thousand signifies the 4 thousand years since Adam
when man was without God, and now God is here. These 4 thousand ate sufficiently,
and were satisfied, and the truth of God was in them. Hunger is part of the virtue
of fortitude. 7 ages of the history of the world, and 7 ages of the Church; and
throughout these ages, the Apostles will have the 7 baskets of fragments to feed
the multitudes until the second coming of Christ. From the time of a man's
baptism until he receives the last sacraments before his death, he will be fed with
the bread of the gospel by the Church, throughout the 7 ages of his life.
