Can "Church" & the "Marketplace" mix?

Christians have used  "Jesus' cleansing of the Temple" (Jn 2:12 - 16) to argue that "Church" & "Business" don't mix.

1. Is the modern day "Church" a representation of the "Temple" ?
    (  I see the "Church" as the "New Israel" rather than the Temple )

2. The early church was always in the Marketplace.
    The "church" was birthed and expanded in the Marketplace therefore  the "Church" & "Business" have
    always mixed. ( It is only in an Institution that that we seek to keep business out ...we have
    compartmentalized our lives instead of seeing life in its whole (Holistic).

(Any discussion, expansion?)
