Udayamperoor
Also known as All Saints Church Diamper
The All Saints Church at Udayamperoor (Diamper) in Ernakulam district, Kerala, 20 kilometres from Kochi — the site of the 1599 Synod of Diamper (Udayamperoor Synod) convened by Portuguese Archbishop Alexio de Menezes of Goa to Latinise the Thomas Christian liturgy, condemn Nestorian Syrian liturgical practices, burn the Syriac books, and formally subordinate the Thomas Christians to Rome. The synod's decrees (26 sessions, 24 June-26 June 1599) produced the first major split in the Thomas Christian community, culminating in the 1653 Coonan Cross Oath against Latin domination. The current church structure dates to 1557 Portuguese construction with major 17-century expansion. ASI partial protection.

Angamaly and Udayamperoor (Diamper) sit 15 kilometres apart in Ernakulam district, Kerala. Angamaly was the medieval Syrian Christian capital of Kerala before the 1599 Synod of Diamper (held at Udayamperoor) Latinised the Syrian Christian liturgy under Portuguese Archbishop Alexio de Menezes. The Angamaly-Udayamperoor pair documents the pre-synod Thomas Christian ecclesiastical hub and the subsequent Portuguese-imposed Latin subordination that produced the 1653 Coonan Cross Oath split.
