Am I a Stoic, or a Christian?

The following quote helps me understand the difference. 

“There is the Stoic's idol, chiseled by austere conscience, from the granitic masses of spiritual strength, and worshipped as the image of divine Justice, Majesty and Holiness. This has won and held captive the noblest spirits that are not wholly Christian, and glorified them to a manliness approaching something divine; yet wanting still the mellowing of pity, and the grace of sweet and glad affections.”

The writer is saying:

There exists a kind of moral ideal shaped by Stoicism — 

severe, 

disciplined, 

carved out of a hard and demanding conscience. 

It portrays God primarily as 

Justice, Majesty, and Holiness — 

strong, stern, and unbending.

This ideal has inspired many noble people who are not fully Christian. 

It has elevated them, giving them great strength, dignity, courage, and self-mastery — almost godlike in moral firmness.

But, the author says, something is still missing:

It lacks pity (tender compassion).

It lacks gentle and joyful affection.

It lacks warmth.

It is strong like granite — but not softened by love.

In worshipping the combination of attributes, through which Christ  has shown us the Father, there can be no fear that any duty will be forgotten, any taste corrupted, any aspiration laid asleep. 

Drawn upward by such an object, nothing in us can remain low and weak: the simplicity of the child, the strength of the man, the love of the woman, the thought of the sage, the courage of the martyr, the elevation of the saint, the purity of the angel, press and strive to unite and realize themselves within our souls.
