Although the chapel was instituted by common will in 1662, only twenty years later the bodies of the founders were placed there (ADV – Governo Civil, Registo Vincular, lv. 6, fls. 38-38v). In fact, the founders determined that their bodies would be buried in the main church of Santa Maria das Chãs until they could be transferred to the chapel they wanted to build next to the house where they lived. This chapel was to be dedicated to São Bernardo, the saint of their particular devotion, and was to have an altarpiece with the specific miracle in which Christ throws blood from the wound in his chest. In the middle of the chapel should be the tomb with the respective grave, where their bodies and those of future administrators would be laid to rest. Six masses should be prayed for their souls every year, one on the day of São Bernardo and the rest throughout the year, giving preference to feast days (*) (ADV – Governo Civil, Registo Vincular, lv. 6, fl. 33v). To fulfill the obligations of the chapel, the respective terças (third part of the inheritance) were named, identifying the immovable assets that should support the charges.
In 1672, Father Pedro Henriques Cabral, abbot of Soito Maior, donates assets to the chapel established by his parents, already administered by his brother Manuel do Amaral Cabral, adding six masses to the respective obligations. The same will be done in 1682 by another brother of the adminsitrator, Father Domingos do Amaral Cabral, abbot of São Bartolomeu de Vila Flor, who not only entailed to the chapel the immovable assets of his patrimony, but also a series of deeds of interest. Part of the income from the interest should be used every year to invest in other interest or in equivalent immovable assets, so that the income of the chapel would always increase. Through this donation he intended that every sunday and holy days there would be mass in the chapel, including in this obligation the masses already determined in previous donations, adding four more masses for the souls of his deceased; as soon as he died, two thousand masses should be said for his soul within two years (ADV – Governo Civil, Registo Vincular, lv. 6, fls. 39-39v).
