The Sodality prayer, Pro devotis amicis, can be found on the sidebar in Latin and in English.
UPDATE: I even beat the press release to it, here it is:
LMS Launches Sodality of St Augustine of Hippo for the Conversion of Lapsed Catholics and Others
Introduction to the LMS Sodality of St Augustine of Hippo.
The purpose of the Sodality is to unite the prayers of members for the conversion of those dear to them. There can be few Catholics today who do not have family members or close friends who have either lapsed from the practice of the Faith, or never had it; it is a particular source of grief when parents see children and grandchildren living without the support of the Sacraments. We take heart from the example of St Augustine, converted at last by the prayers and tears of his mother St Monica, and wish to demonstrate our fellowship with others in the same position, by praying not only for our own dear ones, but for those of others who will do the same for ours.
Sodality members undertake to say every day the prayer Pro devotis amicis, taken from the Roman Missal, for the Sodality’s intention; members who are priests undertake to say one Mass a month for this intention. The intention is the conversion or return to the Faith of family and friends of Sodality members. The intended beneficiaries of our prayers are not listed, except in the hearts of Sodality members. The Latin Mass Society, to which the Sodality is affiliated, will arrange and announce in advance at least one public, Traditional Sung (or Solemn) Mass for the Sodality’s intentions a year.
Sodality members, both lay and clerical, may add other Masses, prayers, and devotions, for the Sodality’s intention, and are encouraged to do so. In particular, members will be asked annually if they wish to make a contribution to the costs of the Sodality’s public Mass or Masses, and whether they would like to make a Mass offering for an additional Mass or Masses to be said for the Sodality’s intention, which the Latin Mass Society will arrange, to be celebrated according to the Extraordinary Form. (The customary Mass Offering is £10.)
Membership of the Sodality is free and open to all; members sign up by email (email@example.com).The Sodality Prayer:
Pro devotis amicis (which may be said in Latin or any other language):Deus, qui caritátis dona per grátiam Sancti Spíritus tuórum fidélium córdibus infudísti : da fámulis et famulábus tuis, pro quibus tuam deprecámur cleméntiam, salútem mentis et córporis ; ut te tota virtúte díligent, et quæ tibi plácita sunt, tota dilectióne perfíciant. Per Dóminum nostrum Iesum Christum Fílium tuum, qui tecum vivit et regnat in unitáte eiúsdem Spíritus Sancti, Deus, per ómnia saecula sæculórum. Amen.
O God, who, by the grace of the Holy Ghost, hast poured the gifts of charity in the hearts of thy faithful, grant to thy servants and handmaids, for whom we entreat thy mercy, health of mind and body; that they may love thee with all their strength and, by perfect love, may do what is pleasing to thee. Through our Lord Jesus Christ thy Son, who liveth and reigneth in the unity of the same Holy Ghost, God, world without end. Amen.
Masses for the intention of the Sodality should include, when possible, the Commemoration ‘Pro Devotis Amicis’ (Collect, Secret and Postcommunion) found in the Roman Missal. Adding such a Commemoration is possible in the 1962 Missal on Fourth Class Feasts at Low Mass, where no more than one Commemoration is demanded by the Ordo.
