The Sacraments are the seven channels of grace instituted by Christ. They are normative. God is not limited in any other manner as to how, when, or to whom He grants His grace, but Christ did not initiate the Sacraments on a goof, or as a dare. Each and every thing He said and did has eternal import.
So Catholics don’t see prayer, listening to preaching/teaching/studying the Bible, singing in worship, giving financially to church and missions , and serving (in church or missions) as a means of grace?
Lanman, maybe you missed the word “other” in this sentence. I have certainly experienced Gods grace through the sacraments. But I have also experienced his grace through all the other things you mentioned. The sacraments don’t tie his hands… For me, one specific huge means of his grace was a Catholic retreat I made in high school, where I first understood that God was asking me to give my whole life to him, to make him first in every part of my life. My every dealing with him is filled with grace, not because of me but because of the abundance of his love. But the sacraments as we understand them are special and are a more certain means of his grace.
Which can be restored through repentance and the sacrament of penance. Jesus says the only unforgivable sin is blasphemy against the Holy Spirit… if you turn you back on God, reject what He offers freely then how can you restore anything in any way… other then that all sins are forgivable.
Also I think Baptisms gives you grace as a baby or when you accept the Lord as an adult. Then Penance repairs your grace when you sin and The Eucharist helps you stay in grace or reminds you of the grace given to you when take in the body and blood of Christ… so I’m thinking the sacraments of baptism gives you grace but the other scraments reaffirms the grace freely given.
Some of the things you mentioned like charity are signs of faith, the Holy Spirit guiding you… living by God will. The reason you do them, only God knows if its cause if the grace He gave you.
The other things you mentioned, like bible reading, going to church… not sure how those are defined other then people should do them to grow in their relationships with Christ. I think it will aldonshownthe grace God gave you is strong or atleast working in you cause you want to do them.
