ACTIVITIES TO BE SCHEDULED. Saint Lambert was a Martyr and a Bishop of Maestricht.  He was born at Maestricht between 633 and 638.  He died at Liège, between 698 and 701. Lambert was martyred because of his defence of the marriage tie. Pepin of Heristal lived for many years in irreproachable wedlock with the pious Plectrude, who bore him two sons. Later he entered into unlawful relations with Alpais, who became the mother of Charles Martel.
