[18][19][20][10] Following the death of Mar Abraham, the padroado Roman Catholics, led by Archbishop of Goa Alexis de Menesis, managed to block the arrival of further Syriac bishops and succeeded in organising the Synod of Diamper, a pseudo-diocesan synod, and forcibly brought the Syro-Malabar Christians under their jurisdiction.

[21] The church, however, retained that cathedral status until Francisco Roz moved the diocesan headquarters to Kodungallur.

The indulgences covered two feasts of the Patron Rabban Hormizd that fell on the fifteenth day after Easter (Monday) and on the first of September.

As requested by Mar Abraham, the Jesuits laid the foundation stone of a new Cathedral Rabban Hormizd in the same place that was chosen by the Metropolitan.

[2] Antonio de Gouvea, in his book Jornada do Arcebispo de Goa Dom Frey Aleixo de Meneses (1606), the travelogue of Alexis de Menezes the padroado Archbishop of Goa who convened the Synod of Diamper, gives an account of the churches in Angamaly: Angamalle (Angamali) has three big churches, the Cathedral had been dedicated to Hermusio (Hormusio) Abbot, a Nestorian heretic, and very important head of this heresy; the Archbishop changed its name to Saint Hormisda, martyr of Persia, which is the same name in the Malabar language, and persuaded the people that that was the Patron Saint of that church, that they were mistaken about the day and the legend of his life, and he ordered the burning of the book on the life of the said Hormusio, for having many errors and heresies, which he first showed to all the Cassanars, which they confessed to be so.Anquetil Du Perron, who visited Malabar in the eighteenth century, gives the following list and description of churches in Angamaly in the country of the Velutha Thavali ruler:[22] He then mentions a fourth church in the country of the Velutha Thavali, which is at Akaparambu and dedicated to Saint Gervasis, co-owned by Syrian Catholics and schismatics.
