On this basis, (which however is) the authentic ancient faith of the Church, we had an over-emphasis (on community), which sometimes arrives even at the denial of the validity of individual religious action. In this way the church building is seen as the headquarters for the reunion of the assembly or community. There a sacred action is performed when the community is present, but it remains an empty shell, and it is not considered to be for use as a personal, individual, “private” place. But the church which has been transformed into a conference room does not need pictures, and even these could be a hindrance. Let us think of a conference hall or a hall used for conventions: the emptier they are, the better they are for the gathering for which they are used since this helps the participants to concentrate their attention on the speakers.. The churches used as assembly halls do not need pictures because pictures do not serve, they even disturb. And this actually goes well with the minimalist and purist taste of many architects, however creative or repetitive they may be.
