The first reading is from Acts (1: 15-26 passim). It is just after the account of the Ascension, which we still celebrate as a feast; it reminds us that though God is still with us in all that we do (except sin) yet He wants us to make our own decisions about the details because He wants us to be friends not blind automatons controlled by Him. So the disciples have to get on with the practicalities of life. They are all Jews and they think that being a follower of Jesus is a renewed way of living as a Jew; so just as there were twelve tribes of Jews according to the Bible, they want to have twelve leaders to help with the organisation of the growing numbers of followers of the Way of Jesus; and the gospels that list the disciples give a list of twelve men. As they consider the replacement of Judas Iscariot they look in their Bible (which Christians now call the Old Testament) and seek there for support for their planned action. They set about to arrange this replacement in the very down-to-earth way of voting, but believe that the Spirit is with them in the doing of this. God leaves us to make our own decisions in our particular circumstances and we should consider prayerfully in the light of our Bible and our beliefs what we should be doing in our lives and in day to day activities.
In the second reading, we once more read of the great love of God for and in us, and the love we must have of others in our world. The reason why this letter repeatedly stresses these points lies in the situation of the church that is being addressed at that time. Some of the people are so caught up with their personal form of holiness that they think this world is all wicked and consequently God didn’t really become one of us, but just appeared to be human in the man Jesus. But the Christian message is that this world here and now is holy. Not only is it being created every moment by God, but also humanity is joined intimately with God through Jesus Who is both human and Divine. But this perfect creative activity of God is in process: it is ongoing and it depends on us – God in some way depends on us! This is because He truly loves us and love never over-rides or forces the decisions of those loved. The world is in the process of gradually becoming what it will; Jesus illustrated in His life, right up to death, how to return God’s love by loving his world – all the people in it – even if that leads to difficulties and death. What an example He has given us, what a challenge we face! But God gives us the strength.
The gospel is part of a whole section from the gospel according to John, comprising long speeches and prayers attributed to Jesus, made after the last supper and before His arrest in Gethsemane. It is thought that different amounts of these were read in the early Christian churches using this gospel, according to the timing of Easter, which then as now, could be early or late according to the lunar calendar. The prayer in this section is for God to protect the followers of Jesus, because it is not easy to live both in the here and now and with the life of God above and in eternity. When this refers to the difficulties of life here, which Jesus had experienced and his followers will now begin to realise, the writer calls this aspect of life here as being in the world: the word ‘world’ here means its failings, short-comings and even at times the opposition to the ideal for God’s work of creation. God Himself and His planned accomplishment is holy; Jesus as one of us is coming to His place in this scheme but the followers are still on the way. To be consecrated is to be united into this holiness; it is a task for the followers of Jesus – for us – for which Jesus here prays
There is a jotting also by me (Jeff Bagnall) which I posted 2 years ago about the feast of the Ascension
