It’s an interesting picture - more that you posted it than the picture itself.
And what does God record using inspired Words about how Christ conducted the Lord’s Supper when he initiated it for the first time?
Gilt? Copper? Shape? Cover? Height?
God didn’t consider it significant enough to describe that it was even in a container, let alone prescribe one. Nor does anyone in attendance worship the matzah bread nor the wine.
The focus was the bread and wine and symbolism. Not the container.
Bergoglio was not doing anything unScriptural in your picture.
Beyond that, it’s all made up later.
"Symbolism"? I assume, you are not a Catholic. Are you?
