I’m speaking of something deeper: of morality. Far too many Catholics think of Christian morality as following the mandates of God which deserve punishment if infringed. The over-preoccupation with distinguishing mortal from venial sin (which is itself a valid distinction), of knowing what is or what isn’t grave matter,
While this juridical understanding is true as far as it goes (it is even used in the Bible), it is not deep enough. The Easterns, and Catholic thinkers in their better moments, have always the deeper understanding in mind: the soul is either turned towards God or away from Him, in the process of being united to Him or trying (in vain) to run away from His Divine Love in search of happiness in a lesser good, where happiness cannot be found. So the focus is on loving God and turning all that we do to His glory, knowing that our true fulfillment can only be found in our union with Him; and not in a cold exercise of following some strict laws and feeling free to do whatever we want where there is no explicit prescription.
Yes, “a cold exercise of following some strict laws and feeling free to do whatever we want where there is no explicit prescription” may qualify as legalism:
Meriam Webster
legalism: strict, literal, or excessive conformity to the law or to a religious or moral code <the institutionalized
legalism that restricts free choice>
Yet Divine Law
is to be followed strictly and is a matter of morality? One does not put on Christ when intentionally violating Divine Law. When you said “the mandates of God which deserve punishment if infringed” are you not speaking of that which results in not inheriting the kingdom of God? Being without heaven in the end is surely conceivable as a punishment:
Matthew 25:41-46:
Then he will say to those on his left, ‘Depart from me, you accursed, into the eternal fire prepared for the devil and his angels. For I was hungry and you gave me no food, I was thirsty and you gave me no drink, a stranger and you gave me no welcome, naked and you gave me no clothing, ill and in prison, and you did not care for me.’ Then they will answer and say, ‘Lord, when did we see you hungry or thirsty or a stranger or naked or ill or in prison, and not minister to your needs?’ He will answer them, ‘Amen, I say to you, what you did not do for one of these least ones, you did not do for me.’ And these will go off to eternal punishment, but the righteous to eternal life."
I Corinthians 6:9-10
Know ye not that the unrighteous shall not inherit the kingdom of God? Be not deceived: neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor abusers of themselves with mankind, Nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners, shall inherit the kingdom of God
Galatians 5:19-21
Now the works of the flesh are manifest, which are these; Adultery, fornication, uncleanness, lasciviousness, Idolatry, witchcraft, hatred, variance, emulations, wrath, strife, seditions, heresies, Envyings, murders, drunkenness, revellings, and such like: of the which I tell you before, as I have also told you in time past, that they which do such things shall not inherit the kingdom of God.
Ephesians 5:5-6
For this ye know, that no whoremonger, nor unclean person, nor covetous man, who is an idolater, hath any inheritance in the kingdom of Christ and of God. Let no man deceive you with vain words: for because of these things cometh the wrath of God upon the children of disobedience.
