It is scarcely possible to conceive that, even if the Christian religion had taken its rise in circumstances altogether dissimilar from those amid which as a matter of history it actually emerged, there would have been no commemoration of such great events as the death and rising again of its Founder. But the first disciples of Christ being Hebrews, and their converts at first being also in a large measure Hebrews, it was inevitable that the great Hebrew festival of the Passover should take to itself a new colouring and a new significance in Christian thought. Thus we find St Paul speaking of Christ as ‘our Pascha’ (_i.e._ Paschal victim), which ‘hath been sacrificed for us’ (1 Cor. v. 7). And he adds, ‘therefore let us keep the feast (_or_ keep festival) not with the old leaven, neither with the leaven of malice and wickedness, but with the unleavened bread of sincerity and truth.’ It would indeed be unwarrantable to infer from this passage that a Christian Pascha was actually observed as a festival at the time when St Paul wrote to the Corinthians. But it is obvious that the passage is steeped in reminiscences of the Hebrew festival, and that these are already receiving a new complexion and a new meaning. The observance of the Christian Pascha first comes into marked prominence about the middle of the second century. At that date it was everywhere a recognised institution of the Church; but there were differences between the Churches of proconsular Asia (the Asia of the seven Churches of the Apocalypse) and the Church at Rome and in other places, as to the particular day upon which the commemoration should be observed. The evidence with regard to the early stages of the dispute is scanty. Such details as we possess are not free from obscurity and have been variously interpreted. In a work like the present volume we can do no more than lay before the student the results which seem to us to have the greater weight of probability in their favour.
