The Ezekiel one was done in Year A during Lent
Romans 8:22-27
The book of Romans spends a lot of time explaining creation and its workings and how people fit into it. In this passage, we hear about Spirit. Sometimes this is written with a lower case "s", giving it a more generic sense, rather than a specific part of the Trinity. In some cases, like verse 27, the Greek might even be "he" or "it". You can make of that what you will.A little more interesting to me is the verses right after these, where it talks about his Son being the "firstborn within a large family" or in some translations "among many brothers". Paul doesn't mention much about Jesus being born, and here it seems more like an allegorical use of "brothers". Early Christians used the term "brothers of Christ" to refer to each other. This allegory and other parts of Paul's epistles are closely in line with a book that didn't make the Bible, The Ascension of Isaiah. It too has a celestial image of God and His first born as his agent, but it more explicitly keeps that agent above the clouds.
I would be remiss if I didn't also say a few words about "first fruits". This is an Old Testament concept, the first fruits of the harvest. God commanded that these be offered to Him. Actually, that meant they would be given to the Temple. They said this would guarantee the rest of the harvest would come in, but it was basically a tax. Paul is using this as a metaphor for these new converts to this new covenant, that they are the guarantee that redemption will come to more people.
John 15:26-27; 16:4b-15
We get a little more about "spirit" in this one, and also this "advocate". Other translations of parakletos are "helper" or "counselor". It seems to be used here as a lawyer in court, arguing your case for you. This excerpt is within an address that began in chapter 13 and goes through 17. We aren't getting a lesson in the law here, but told of assistance in time of need.There's an odd verse at 16:5, where Jesus says he's going, but "none of you asks" where. I imagine this said slightly under his breath, but that's probably just my interpretation. This is probably more specific to this particular audience, for whatever reason, they had not yet made this inquiry. Either way, Jesus consoles them. It's good he's going, because that's how he will send the "help". He lists sin, righteousness and judgment and gives terrible explanations about what is going to be done about them. He does even worse with truth. You can kind of see where ideas about the Trinity came from in the last few verses, although it's doubtful that's what the original author had in mind. The Trinity is notoriously difficult to explain, just like this passage.
