Rest in the mystery of Christ's dual nature that you might have the constant consolation of truth rather than the doubt of crafty reasoning...

Since in the Holy Scriptures Christ is called a mystery upon which all heretics dash their heads, we admonish all Christians not to arrogantly indulge their reason in crafty investigations about such mysteries.  With the beloved apostles, they should simply believe.  They should close the eyes of their reason and bring their understanding into captivity to the obedience of Christ, and rejoice without ceasing in the fact that our flesh and blood is placed so high at the right hand of God's majesty and almighty power.  In this way we will certainly find constant consolation in every difficulty and remain well guarded against deadly error.
~BOC, FSD, VIII, 96

Christ, in both natures, is with us in all our troubles...

When such majesty is denied to Christ according to His humanity, we regard it as a deadly error.  For by this the very great consolation mentioned above is taken from Christians, which they have in the promise about the presence and dwelling with them of their Head, King, and High Priest.  He has promised them that not only His mere divinity would be with them (which to us poor sinners is like a consuming fire on dry stubble).  But Christ promised that He—He, the man who has spoken with them, who has experienced all tribulations in His received human nature, and who can therefore have sympathy with us, as with men and His brethren—He will be with us in all our troubles also according to the nature by which He is our brother and we are flesh of His flesh.
