What does it mean?

I've been learning vocabulary used in the Christian world.

Communion or Eucharist: the Lord's Supper, also known as "the sacrament" in the LDS church

Exegesis: Greek for "lead out of," an explanation or interpretation, especially of the Bible

Indwelling: having the Holy Spirit living within us

Intercession: praying for others

Minister: Latin for "servant;" someone who is ordained as clergy

Ordination: recognizing and confirming that someone is called to the ministry, has been trained and authorized to teach and perform services like weddings and funerals. (The LDS church teaches that ordination imparts special authority and power from God and their ordained clergy are not trained in theological seminaries.)

Nicene Creed:  We believe in one God,
the Father, the Almighty,
maker of heaven and earth,
of all that is, seen and unseen.
We believe in one Lord, Jesus Christ,
the only Son of God,
eternally begotten of the Father,
God from God, Light from Light,
true God from true God,
begotten, not made,
of one Being with the Father;
through him all things were made.
For us and for our salvation
he came down from heaven,
was incarnate of the Holy Spirit and the Virgin Mary
and became truly human.
For our sake he was crucified under Pontius Pilate;
he suffered death and was buried.
On the third day he rose again
in accordance with the Scriptures;
he ascended into heaven
and is seated at the right hand of the Father.
He will come again in glory to judge the living and the dead,
and his kingdom will have no end.
We believe in the Holy Spirit, the Lord, the giver of life,
who proceeds from the Father and the Son,
who with the Father and the Son is worshiped and glorified,
who has spoken through the prophets.
We believe in one holy catholic and apostolic Church.
We acknowledge one baptism for the forgiveness of sins.
We look for the resurrection of the dead,
and the life of the world to come. Amen

Pastor: "shepherd," a title for clergy, like a minister

Trinity: one God who exists as three persons (I'm having trouble wrapping my mind around this after decades of the LDS doctrine of the "Godhead." It blows my mind that I can pray to Jesus too.)

Witness: give testimony of Christ
