The division of Church property in three parts is postulated e.g. by Canon 7 of the First Council of Braga in AD 561 [304]. One part is for the bishop, another for the clergy, and the third for the restoration of the churches. Apparently the exaction of the third part of the parish property by the bishop became very burdensome for presbyters, and they complained at the councils. Already the Second Council of Braga in AD 572 set limits on the amount of money that might be demanded from parishes by a bishop [329]. The Seventh Council of Toledo in AD 646 referred to the rulings of Braga in response to complaints by Galician presbyters who felt oppressed by the financial demands of their bishops, and that in consequence the churches were going to rack and ruin. The present canon of the Council of Mérida bears witness to a similar situation in the province of Lusitania. The problem of the ruined basilicas in the country must have been serious enough that the bishops agreed to resign from a part of Church revenues that had traditionally been due to them in order to finance renovation works and maintenance.
The canon speaks about "the above-mentioned presbyters" most probably because the former canon also refers to bishops and presbyters, or because the authors of the canon referred twice before to the "parish churches", which, implicitly, were led by the presbyters.
