The English word session refers to a time of sitting or, more specifically, sitting to conduct certain business. A Parliament or law court can sit or be “in session”, for example. A group of beer drinkers or musicians can be “in session”. Presbyterians call the board of elders or consistory in a local church the church or kirk session.
We know that Christ is now in session because this truth is taught not only in Psalm 110 but also in several other places in the Bible. Psalm 110, however, is original and fundamental.
From my book What Jesus is doing now, p 58
