The Mystery of the Trinity, Part 3

The Trinity is just one of those things that most Christians just don't know what to do with. Sure, they know it's important to the Christian faith but it just doesn't seem practical. It's that thing that theologians and PhD students argue about that probably matters but ultimately just confuses things. Our typical solution has been to ignore the Trinity, leading to the perception that it really just isn't that important.

This couldn't be further from the truth. (Read Parts One and Two to be caught up!)

The Trinity is the beating heart of the Christian life. It is inexorably connected with the person and mission of Jesus Christ. It is the very life of God, and it is the wellspring of our life as well. Too often the Trinity is treated as an abstract hypothetical when in fact it is the very basis of all Christian thought and practice.

Let's start at the beginning of the Christian life; baptism. When you are baptized it is in the name of the Father, Son, and Holy Spirit. That is the name of the covenant you have entered. At baptism we are joined with Christ and his people, our sins are washed away, and we die to walk again in new life. It is a new way of existing, of living, and it is all because of the Triune God.

Baptism isn't special because of the water or even our actions. Baptism is meaningful and powerful because of God. At baptism the Holy Spirit indwells us, cleansing us of our sin and joining us with the Son so that we may stand before the Father as sons and daughters. It is this one, mysterious act of God's grace that saves us. From that moment on we are called to be Father, Son, and Holy Spirit people.

The next fundamental piece of the Christian life is the Lord's Supper. Much like baptism, there is nothing special about the bread or cup. What is powerful and meaningful is God's action through the event. We often call the Lord's Supper "Communion" for a reason; it is an invitation to "commune" with Jesus.

When believers, united and worshiping in the Spirit, celebrate the Lord's Supper Christ is there. He invites us to come to the table of mercy, to renew the covenant we made at baptism with a meal. We proclaim the Lord's death, a solemn call to be faithful to our baptismal covenant in which we were united to Christ in that same death. Together, in the Spirit, we commune with the Son so that we may glorify the Father.

The list goes on and on. I could talk about worship, marriage, celibacy, Bible study, prayer, fasting, serving others, and more. Hopefully the point has been made clear; the Trinity sits at the very heart of the Christian faith. I most certainly will revisit this topic many times in the future, but for now I encourage you to reflect on the Trinity, on its mystery and importance, and think on just how much it matters that we start talking about who God is.

Be Kind

This last Sunday I was asked to preach and I struggled for a while with what to preach on. It's always difficult when you are filling in and everyone else knows you are filling in. You don't want to overlap too much with the current sermon series, but you also don't want your topic to be so unrelated to what's been going on that it has no impact.  I found inspiration simply from scrolling on Facebook. People, and it seems especially Christians, are mean.  Now of course not all Christians are rude and combative, but there are a shocking number who are. We argue in Facebook comments, send hateful messages, and generally act just like the world. This extends beyond the realm of social media and into our day-to-day interactions with so many. The Sunday lunch crowd at restaurants is infamously the worst tipping and most disrespectful, and these are mostly Christians who have just come from church. We need to be kind. Kindness is a fruit of the Spirit, but it is one we often ...

Justice

Our view of justice is narrow and limited. Typically when we, as Christians, talk about justice we are really only referring to punishing wrongdoers for their crimes. While that is certainly a part of justice that isn't the only thing. In the Bible justice consists of much more. Consider the book of Amos, one of the minor prophets and therefore a book that most Christians barely touch. Amos is announcing judgment against the nation of Israel for their infidelity to their covenant with God. What do you think is the most repeated indictment against Israel? Interestingly it's not idolatry, sexual immorality, or war although these things are mentioned. The primary sin of in Amos is Israel's neglect of the poor and their oppression of the needy. Over and over again Amos declares that judgment is coming to Israel because of their treatment of those less fortunate. The poor are trampled and the needy are crushed. There is no justice in the land. Biblical justice includes both crim...

Jesus or Nothing

"Non Nisse Te Domine." - Thomas Aquinas I have the above quote engraved on the bottom of a watch that my father gave me several years ago. It means "Nothing if not you, Lord." Thomas Aquinas, 13th century monk and one of the most influential theologians and philosophers in all of history, said this after having a vision of Jesus. Reportedly Christ appeared to him and said "You have written well of me, Thomas. What what you have as a reward?" "Non nisse te Domine," was the response. After that, even though Thomas had dedicated his life to writing theology and was in the middle of writing his massive Summa Theologia, Thomas stopped writing. He said it was because all he had written, tomes and tomes of brilliant work, were as straw compared to seeing the actual Lord. Whatever you may think about such a mystical event, I personally believe it happened but I understand the more skeptical among us, the response of Thomas is what matters. When asked for...
