A new catechism on the Trinity is the focus of the new addition of Credenda Agenda. The focused catechism was for the purpose of "filling gaps" of older catechisms. It seems that Wilson does not find the historical catechisms to suffice on this head of doctrine. His catechism is poetic as well as in a biblical form called iambic pentameter and chiasm. (I will not explain, but may do a post on this later). Below is a section that I have found to be an appropriate meditation on the relationship of Christ to the Church. It is a marvelous piece to meditate upon. How could the dirtied bride enter the Son's wedding?
Christ killed her sin upon His bloody cross;
Like Father and the Spirit, triune life
is death and gift, a dance of sacrifice.
Where did the Son take her? What does she do?
United to His wife, He raised her from
the dead, ascended into heaven, and joined
the dance, the fellowship of Trinity.
How can the bride not fall again, like in the Garden or the desert?
Unlike Mosaic saints, who strained without
a will, God poured the Spirit in His Church,
empowering us for loyalty and love.
What is the purpose of this marriage of Son and Church?
This new Adam and Eve pick up the work
abandoned by the first to raise a godly
seed, expand the feast, and build a garden city.
How does God send us from the wedding?
He loads our arms with water, wine, and bread
and sends us cheering down the highway,
to fill the wedding hall with guests.
