Compare Traditions on One Technology
Choose a technology and read the traditions' recorded stances side by side — each with its rationale in its own terms. The comparison is the section's method in one view: the differences are in the reasons.
Heliocentric astronomy
The moving earth: proposed by a priest-astronomer of Alexandria, published by a canon of Frombork, condemned as advocacy in 1633, and measured as fact in 1838. The full register entry
Catholic
Contested within the tradition
The Church that condemned Galileo’s advocacy in 1633 had received Copernicus’s dedication in 1543 and employed heliocentrists’ mathematics in the calendar reform. The institutional record runs from patronage through disciplinary error to formal acknowledgment: the 1992 address of John Paul II closed the case by naming the theologians’ mistake — treating a contested cosmology as a matter of faith.

Jewish
Embraced
Maimonides had already laid down the rule that governs the case: astronomical questions belong to demonstration, and where demonstration and the plain sense of Scripture conflict, Scripture is reinterpreted — as he himself handled the spheres. Jewish astronomers (Gersonides among the greatest of the medieval observers) worked inside the question without a communal ban.

Mainline Protestant
Embraced
Kepler held the heliocentric system as a Lutheran and argued it theologically: the sun as image of God the Father in a cosmos built on geometrical harmonies. No Lutheran body condemned the system; its difficulties in Protestant lands were academic before they were doctrinal.
