I can imagine this being accomplished THROUGH religious orders rather than in spite of them. For instance, suppose that a Christian sect appears in the 4th century that emphasized acquisition and entrepenurial use of resources to feed the poor. As part of the manastic teaching, science & economics become integrated into religious teaching. The Church also provides capital for businesses to start-up both within the confines of the Church as well as for parishiners. As the Vikings start invading mainland Europe, and while everyone else presses toward a feudal system, the countries that have adapted this flavor of Christianity will develop weapons and systems to defeat the Viking invaders. Early crossbows and development of "mines" and projectiles will help drive mathematics & science as well as mechanics.
There were medieval monastic orders who built lots of windmills and other machines. They had an article about them in the Wall Street Journal some years ago.
The start-up capital for businesses could be viewed as a way of helping the poor. Jesus's position on generosity taken to a level above personal giving.
