[Petrosius]

One reason to accept the doctrine of Consubstantiation:

While they were eating, Jesus took bread, said the blessing, broke it, and giving it to his disciples said, “Take and eat; this is my body.” Then he took a cup, gave thanks, and gave it to them, saying, “Drink from it, all of you, l for this is my blood of the covenant, which will be shed on behalf of many for the forgiveness of sins." (Matthew 26:26-28)

Jesus said it. All human objections are meaningless.

"60Therefore many of His disciples, when they heard this said, "This is a difficult statement; who can listen to it?" 61But Jesus, conscious that His disciples grumbled at this, said to them, "Does this cause you to stumble?…"

Come home.

And it just gets more and more interesting.

Calvin's actual teachings and acts lead a Protestant history scholar to become a Catholic.

I was especially interested to read his claim that Calvin repudiated a "Spiritual" sense of the Eucharistic presence.
