‘[W]e have heard and received report from the relation of diverse rumours that your bishops are not at all in harmony with the rule of the Catholic Faith according to the precepts of Scripture, and, on account of their animosities and verbal assaults, a grave schism and cruel scandal may arise in the Church of Christ, which the maxim of the Psalmist detests that says, “Much peace have they that love thy law and to them there is no stumbling block”. For truly, obedient harmony in religious matters unites with charity, just as harsh strife contaminates it. For the Psalmist enjoins the unity of brotherhood upon the followers of truth, saying, “God who maketh men of one manner to dwell together in a house”. This house, according to allegory, is understood to be the Church, spread throughout all points of the world. For indeed, heretics and schismatics, foreign to the society of the Church, sprouting up in the world and like, so to speak, the dreadful seed of darnels sown in the midst of a fertile crop, defile the harvest of the Lord by their contentious arguments. But the Apostolic Trumpet [Saint Paul] curbs the disgrace of altercation of this sort: “But if any man seems to be contentious”, he says, “we have no such custom nor does the Church of God… which does not have spot or wrinkle”. Indeed, the evangelical oracles proclaim that peace is the mother of Catholics and the authoress of the children of God’.
from a letter to King Geraint by St Aldhelm, c.639-709
O God, who as on this day didst exalt thy blessed Bishop Saint Aldhelm to everlasting felicity: we pray thee; that by his merits and intercession, thy mercy may bring us unto that place whither he is gone before; through Jesus Christ thy Son our Lord, who liveth and reigneth with thee, in the unity of the Holy Ghost, ever one God, world without end. Amen. - Divine Worship: The Missal.
