The Ecumenical Society of Saint Augustine of Canterbury (TESSAC) is a Priestly Society without vows, whose purpose is the Priesthood and that which pertains to it. TESSAC comprises clergy and missions and was founded by The Right Reverend Robert C. McBride BA (Hons), OSP on the Feast Day of St Martin, I, Pope and Martyr, 12th of November in the year of our Lord 2008. TESSAC is not a member Society of any mainstream church, such as the Roman Catholic or Orthodox Churches, but does share in their Apostolic Successions.

Our Ecumenical outreach extends to those ecclesial communions who can clearly trace their lines of apostolic succession back through the historic episcopacy directly to our Lord Jesus Christ and His apostles and who are holding to historic, apostolic catholic and orthodox order and practice in their faith and worship, as defined by the ancient and undivided Church, reflected in the teaching of the first seven ecumenical councils of the early Church.

We further believe that God has commissioned us to affirm, recognise, and pray for all of these branches as members of the One, Holy, Catholic and Apostolic Church and to embrace and receive the clergy and laity of all these branches as true brothers in the communion of Christ's One, Holy Church, His body in heaven and on earth.

We believe that God has called us by the grace and mercy of our Blessed Lord Jesus Christ, to be at least a prophetic pointer of a prototype of such unity, both in an underlying attitude of humility and charity, as well as by the works, worship and mission that we pray constantly, bear witness to that divine hope and calling with open minds and hearts.

In practical terms this unity, or prototype of unity as Catholic Christians, will be worked out in our embrace of a diversity of historic, orthodox catholic liturgies, as used by the major branches of Catholic and Orthodox Christianity from the beginning.

These include the Divine Liturgy celebrated by our Orthodox Brother Bishops, the Tridentine Liturgy (Latin /The Vernacular) and Novus Ordo of the Roman Catholic Church; Traditional Anglican Liturgies; Western Rite Orthodox Liturgies, and others recognized as expressions of rites used historically within the broad scope of orthodox, catholic Christianity worldwide.

Mindful that Saint Augustine of Canterbury was sent to these Islands to spread the Word, and establish the Faith, TESSAC seeks to continue with this work as we enter an age where people are abandoning their faith and instead become secularised. Members of TESSAC take their stance upon a shared vision of a disciplined priestly life fashioned after a definite spiritual rule. It is this Rule of Life which unites the Brethren in their various priestly ministries and lives.

The Brethren are required to consider their obligation to the Society as a close spiritual bond which takes precedence to that of any other voluntary society.  This obligation includes a commitment to attend TESSAC Chapter meetings and other Synods.  The life of the Society is experienced primarily through the Chapter, and attendance at Chapter is of obligation unless prevented by genuine pastoral duties.

Saint Augustine of Canterbury struggled in his mission but in the words of Pope Gregory The Great, in a letter to Saint Augustine: "He who would climb to a lofty height must go by steps, not leaps," therefore we too take comfort from and are guided by those words, aided and guided by our Rule of Life, as we work to continue Saint Augustine's work in the 21 st century.romising start, Augustine went back to Provence to be consecrated bishop by Vergilius, metropolitan of Arles and papal legate for Gaul. On his return some ten thousand of Ethelbert's subjects were baptized in the Swale River.

Augustine, greatly heartened by the success of his mission, now sent two of his monks to Rome to report to the Pope, and to ask for more helpers. Also he wished to have the Pope's counsel on various problems. When the monks came back to England with a fresh band of missionaries, they brought the pallium for Augustine. Among the new group were Mellitus, Justus, and Paulinus, who was afterwards archbishop of York. With these "ministers of the Word," wrote the Venerable Bede, "the holy Pope sent all things needed in general for divine worship and the service of the Church, viz. sacred vessels, altar cloths, ornaments for churches, and vestments for priests and clerks, and also many books." The latter item was especially important, for the books helped to inspire the great love of learning which characterized the English Church.

Gregory sent to Augustine a plan for developing an ecclesiastical hierarchy and establishing a working organization for the whole country-a plan which was not fully carried out in Augustine's lifetime. There was to be a northern and a southern province, with twelve suffragan bishops in each. In a letter to Mellitus, which is presented earlier, following the life of St. Gregory, he gave instruction on other points, showing his administrative ability as well as considerable psychological insight. Pagan temples were, as far as possible, to be Christianized and retained. Consecration rites and feasts of martyrs were to replace the heathen festivals, for, Gregory wisely writes, "he who would climb to a lofty height must go by steps, not leaps."

In 603 Augustine rebuilt and reconsecrated the Canterbury church and the house given him by King Ethelbert. These structures formed the nucleus for his metropolitan cathedral. They were destroyed by fire in 1067, and the present cathedral, begun by the great Lanfranc in 1070, stands on their site. A converted temple outside the walls of Canterbury was made into another religious house, which Augustine dedicated to St. Peter and St. Paul. After his death this abbey became known as St. Augustine's.

With the King's support, the Christianization of Kent proceeded rapidly, but Gregory's charge had stated, "All the bishops of Britain we commend to your Fraternity." The survivors of the ancient British or Celtic Church and their bishops had been driven westward and southward into Wales and Cornwall by the Saxon conquerors of the fifth century. Here they had persisted as Christian communities, cut off from the outside world. Although they were sound in fundamental doctrine, some of their usages were at variance with those of Rome. Now, in virtue of his archiepiscopal jurisdiction, Augustine invited the Celtic bishops to meet with him at a spot outside the confines of Wessex, which has since come to be known as Augustine's Oak. In long conferences with the representatives of the Celtic Church Augustine urged them to comply with the customs of the rest of Western Christendom, in particular in the method of determining the date of Easter, and to aid him in converting the pagans. Loyalty to their own local traditions, however, and bitterness against their Saxon conquerors, made them unwilling to agree, even though Augustine performed a miracle of healing in their presence to prove the supernatural source of his authority. They consented to attend a second conference, held in Flintshire, but it too proved a failure. Augustine did not rise to greet his Celtic brothers when they arrived and they felt that he lacked Christian humility. They refused either to listen to him or acknowledge him as their archbishop. It was not until 664, at the Synod of Whitby, that their differences were resolved and ecclesiastical uniformity was established.

Augustine's last years were spent in spreading and consolidating the faith in Ethelbert's realm, which comprised large sections of eastern England south of Northumbria. Sees were established in London and Rochester, with Mellitus appointed bishop over one and Justus over the other. Seven years after his arrival Augustine died, leaving the continuation of his work to others.

+Prayer for Saint Augustine of Canterbury+

O God, Who by the preaching and miracles of blessed Augustine, Thy Confessor and Bishop, didst vouchsafe to shed upon the English people the light of the true faith; grant that, through his intercession, the hearts of those that have gone astray may return to the unity of Thy truth, and that we may be of one mind in doing Thy will.

Through our Lord Jesus Christ, Thy Son, Who liveth and reigneth with Thee in the unity of the Holy Ghost, one world without end. Amen.

3.  The call of Christ invites us to take up the Cross, and to follow in the way of the Cross, in faithfulness and obedience to Christ, and in union with him, even to death, and beyond death.
