Shall we rephrase to "is building"?

De Maria said:

Scripture tells us that there is an infallible Church out there which Jesus built.

Lutero responded:

De Maria

As the Scripture says:
Ephesians 2:20

King James Version (KJV)
²⁰And are built upon the foundation of the apostles and prophets, Jesus Christ himself being the chief corner stone;

Shall we understand this to be a metaphor?

Lutero

DM.......interesting how you pervert that. You give lip service to Jesus being the chief corner stone, yet in practice you deny his authority in the churches. You are a deceiver .

De Maria
That makes no sense. It is because I believe Jesus that I follow the Church which He established. What is your excuse for rejecting the Church which Jesus built?

Luke 10:15-17
King James Version (KJV)¹⁵And thou, Capernaum, which art exalted to heaven, shalt be thrust down to hell.¹⁶He that heareth you heareth me; and he that despiseth you despiseth me; and he that despiseth me despiseth him that sent me.¹⁷And the seventy returned again with joy, saying, Lord, even the devils are subject unto us through thy name.

Sincerely, 

De Maria
