It was suggested to the missionaries that permission would more likely be obtained if a request was made by the Christian community of Calcutta for a Protestant place of worship. A memorial to the Governor-General was drawn up by Joshua Marshman. During April he visited the principal inhabitants of Calcutta, not in the public service, and obtained more than 100 signatures to it. To the great delight and surprise of the missionaries permission was granted within a week for construction to proceed.

On 1st January, 1809, the desire for a chapel in Calcutta for the English and native congregations was accomplished. The chapel in Bow Bazaar was opened by Carey on that day. It was a spacious, lofty, and elegant edifice, with a gallery on 3 sides, and a noble portico at the front entrance. It was the third Protestant, and the first Dissenting chapel in Calcutta.

Three months after the chapel had been opened the English congregation increased to 200.
