Tabarnacle vs Tabernakulo

The first time I encountered this eerie similarity was when I put up a research regarding the similarity of INC and mormon architecture (http://pasugo-1914.blogspot.com/2008/09/felix-manalo-and-mormons.html). I asked an INC I know what the name and function of the tent-like structure because I wasn't content with just referring to it as "the tent-like structure" to desctibe what's behind the INC temple. I was surprised to find it named exactly the same as the Mormon structure I was comparing it with. Well, the similirities, as it turned out does not stop there.

INC Tabernakulo:
Height 22.5m (73.8 ft)
Width 150ft
Length 300ft
No. of Columns: 48
Seat Capacity: 4000

LDS Tabernacle:
Height 80ft
Width 150ft
Length 250ft
No. of Columns: 44
Seat Capacity: 8000

Now, see how INC describe their Tabernakulo:

and compare it with how LDS describe theirs:
