Our Old Testament reading today tells of the visit of the three men to Abraham: ‘And the Lord appeared to him by the oaks of Mamre, as he sat at the door of his tent in the heat of the day. He lifted up his eyes and looked, and behold, three men stood in front of him. When he saw them, he ran from the tent door to meet them, and bowed himself to the earth, and said, “My lord, if I have found favour in your sight, do not pass by your servant’. We should note the ‘three’; yet, Abraham uses the singular ‘my lord’.

St Ambrose comments on this text, linking it with the young men in the furnace: ‘The heathen king saw in the fire, together with the three Hebrew children, the form of a fourth, like as of an angel, and because he thought that this angel excelled all angels, he judged Him to be the Son of God, Whom he had not read of, but in Whom he believed. Abraham, also, saw Three, and adored One’.

This text of St Ambrose has been taken up in the Church’s liturgy as relating to the Most Holy Trinity. May this Sunday, a day dedicated first of all to the worship of God, be a real day of worship for you, a day of adoration and thanksgiving. May the ‘Three’, as St Elizabeth of the Trinity called them, bless you and keep you in His love.
