Sanctification

 Per this beautiful hymn:

You have united, O Lord,
your divinity with our humanity
and our humanity with your divinity;
your life with our mortality
and our mortality with your life.
You have assumed what is ours,
and you have given us what is yours,
for the life and salvation of our souls.
To you, O Lord, be glory forever.

– From the Maronite Eucharistic liturgy

This is what is real and worthy of our attention and absorption into our intellects. Jesus established His Church for two reasons

Salvation
Sanctification

not for the laity to participate in synods which is Congregationalism for Catholics
