I think I know what you mean here, but was not the act of eating the steak the action of disobedience which has been classified a mortal sin?
No. ‘Eating steak’, per se, is not mortal sin. If there is sin here, it comes from a different consideration.
Some here have given particular interpretations, but they leave out some important notions or conflate the salient issues. Some simply reply ‘yes’, others ‘no’, and still others have attempted to help you understand what the church teaches. Yet, you continue to ask, so it seems that more explanation is necessary.
First, there is a difference between ‘grave matter’ and ‘mortal sin’. You seem to be aware of this, by framing things up in terms of ‘full knowledge’ and ‘deliberate consent’. Yet, you seem to want to caricature this situation as “Catholics think that eating steak condemns a person to hell.” :nope:
This caricature seems to want to ridicule the Church by trivializing her teachings. I assure you, the teaching isn’t as absurd as you make it out to be. Let’s look at it in detail…
You pose the situation as something that seems trivial: ‘eating meat on Good Friday’. Let me ask you a question: what was the sin of Ananias and Sapphira? Was it really simply that they held money back? Or, was it that they bore false witness to the Church and their faith? That is, the capital sin that they committed was that they claimed to be Christian, but refused to live out their faith through their actions.
In Mt 16:19, Jesus tells Peter (alone) that what he looses on earth will be loosed in heaven, and what he binds on earth will be bound in heaven. Therefore, what Peter binds, God binds. So, when one disobeys Peter’s authority… whose authority is he really disobeying?
As some have mentioned, the rule of Lenten abstinence is a rule of the Church – that is, it is a rule instituted by those to whom Peter has passed the mantle of authority (see Acts 1 for a Scriptural example of ‘apostolic succession’). Therefore, one who disobeys the rule of abstinence… disobeys what is bound in heaven.
Now, on the face of it, your story seems like a rather trivial misstep that is punished harshly. Yet, by your telling of it, the person has said, “I know what the Church teaches, and I know that what the Church binds is bound by Jesus… but hey – I’m gonna disobey here and eat meat anyway.” In other words, what the person is saying isn’t simply “I want a nice steak”, but rather, “Jesus, I really don’t care that this is what you’re holding me to – I’m gonna do what I want, simply because I want it.”
So, you tell me: do all who merely cry out “Lord, Lord!” inherit the kingdom of heaven, or are there those who cry out “Lord, Lord!” and do not enter into the kingdom of heaven?
