Matthew 28:16-20The very mark of a Christian is defined by one's solemn confession of the Most Holy Trinity. That's why in all things that we do, we start and end "In the name of the Father, and of the Son, and of the Holy Spirit."
What does it mean to speak "In the name of" the Most Holy Trinity?
To know the name of another means three things:
1. I've developed a sense of deep intimacy and familiarity with the other, "I know him by name";
2. I know his/ her attributes and come to respect them with my life;
3. I give the other what is due - praise, respect, love.
When I start praying "In the name of ..." I should already have a deepening sense of intimacy, closeness or familiarity with God who reveals to me as "Father, Son, and Holy Spirit."
I should know His every attribute, the Father as Creator, the Son as Redeemer, and the Spirit as Advocate and what He means to me and my life.
Third, that I am moved to love, adore, and serve him with my whole life.
Every Christian that make up the Church should be the direct mirror of the Father, the Son, and the Holy Spirit.
