Why would you send a flyer condemning what you (your group) feel is ugly? If the exterior of a building is not "traditionally" attractive, yet its interior inspires and uplifts people to be moved toward a closer relationship with God, why the condemnation?
Jesus used a simple upper room for the Last Supper. He used knolls and the desert as his pulpit. Your flyer and your website appear to be very arrogant and judgmental. To assume "traditional" architecture is the best for our churches reflects a lack of depth of understanding how the heart can be moved by God. Ultimately, its the people who gather who uplift and proclaim God’s greatness. The church is not simply a monument, but a tool to help people become community who gather not only for the sacred, but to proclaim with joy thanksgiving for the gifts God gives us.
There is no need to "restore" beauty to our churches. Rather, the need seems to be for you to restore your relationship with God, without the "crutch" of architecture. When the community becomes as high or a higher priority than the building, you will then have your priorities in order. You don’t seem to understand the theology that acknowledges the value of the community. That is the good and genuine theology expressed in Vatican II.
This is really funny since usually architects and liturgist use the excuse for their Church designs as ways of enhancing community. That the church in the round concepts reinforce the church as community. Now this priest wants to say that the church architecture doesn’t matter at all and we only need to restore our relationship with God. While there is a partial truth in this it forgets the fact that we are body and soul and that the church needs to reflect these aspects also. But at the same time he was saying that this modern architecture can uplift people. Isn’t he trying to have it both ways here?
Visual beauty can reinforce spiritual truth. I have heard and read many conversion stories where people who first found themselves attracted to the beauty of a Church later found the beauty in the truth of the Church. Have you ever heard a similar conversion story that started out with an attraction to a cement box style building? Most of use are not like the desert fathers who can find God easily in a stark dry environment. If beautiful architecture is only a crutch then it is a crutch that is needed to help us stand upright in worship of God. If is rather difficult to read the Old Testament and to come to the conclusion that God expressed no preference in liturgical architecture whether it be a tent or a temple. King David was rebuked not for wanting to build a temple for God, but because he was not the person to do it and it was passed down to his Son to do. If it was only a matter of a spiritual relationship with God then no building would have been erected and no details such as the Ark of the Convenent would have been given. Instead we had explicit details as far as the wood used, how it was to be covered and gold and that statues of angels were to be placed above it.
Thank you for letting me make a comment on your "mission." It appears you choose to cast judgement, rather than allow all people to find the path to God that is most fulfilling.
I hope God will bless you and guide you to a more enlightened form of ministry.
