To begin to understand Our Lord, Jesus Christ, we begin with who God is:
God, infinitely perfect and blessed in himself, in a plan of sheer goodness freely created man to make him share in his own blessed life. For this reason, at every time and in every place, God draws close to man. He calls man to seek him, to know him, to love him with all his strength. He calls together all men, scattered and divided by sin, into the unity of his family, the Church. To accomplish this, when the fullness of time had come, God sent his Son as Redeemer and Savior. In his Son and through him, he invites men to become, in the Holy Spirit, his adopted children and thus heirs of his blessed life. ~Catechism of the Catholic Church #1
As we recite in the Nicene Creed, our Lord Jesus became incarnate of the Virgin Mary and became man. He was crucified and died for our salvation:
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,
one in Being with the Father.
Through him all things were made.
For us men and for our salvation,
he came down from heaven:
by the power of the Holy Spirit
he was born of the Virgin Mary,
and became man.
For our sake he was crucified
under Pontius Pilate;
he suffered died and was buried.
On the third day he rose again
in fulfillment of 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.
Depending on your own background the above statements may sound vaguely familar, a little odd, or completely insane!
That’s okay. As part of the Church that Jesus founded, we’re here to help you learn more, so that the day will come when you can make the same profession of faith that we do.
