In 1623 Lynde published An Account of Bertram the Priest, with Observations concerning the Censures upon his Tract, “De Corpore et Sanguine Christi.” This was intended as an introduction to a tract against transubstantiation by Ratramnus, of which English translations had appeared in 1548 and 1582, and another, by William Guild, came out in 1624.
He was therefore invited to defend the doctrine of transubstantiation against the attacks of Berengar of Tours.
This is what is meant by Real Presence within the Roman Catholic tradition; the presence of Jesus in the Eucharist, although other Christians (notably Anglicans, Old Catholics, Mar Thoma, and Lutherans) accept the doctrine of the Real Presence, whilst rejecting transubstantiation as a philosophical concept.
His conference with Stillingfleet gave rise to the publication of several controversial pamphlets, and ‘The Summ of a Conference on Feb. 21, 1686, between Dr. Clagett and Father Gooden, about the point of Transubstantiation,’ was published in 1689–90 by William Wake.
The necessity of receiving the sacrament as a qualification for office was repealed in 1828 under George IV and all acts requiring the taking of oaths and declarations against transubstantiation were repealed by the Catholic Relief Act 1829.
