@King J. -- maybe More to the point of all of this discussion -- Are my actions bringing glory to God or aren't they? There Are sins or A sin that Can lead to death. What am I doing in "My" life. And in the process of living amongst Others -- what are we seeing in Their lives. Are we concerned enough about Their welfare to quietly say something to them in a concerned way?
Galations 5 :13 "For you, brethren, have been called to liberty; only do not use liberty as an opportunity for the flesh, but through love serve one another. vs 14 For all the law is fulfilled in one word, even in this: "You shall love your neighbor as yourself." vs 15 But if you bite and devour one another, beware lest you be consumed by one another. vs 18 but if you are led by the Spirit, you are not under the law. , Then follows vs 19 Now the works of the flesh are evident, and that passage continues to name a multitude of sins. But No where do I see a mention of 'veniel'' or "mortal" sins.
Now we can look at 1 John 5:16 - 19 The passage that talks about a sin leading to death. My Bible has a cross reference to Matthew 12:31 "Therefore I say to you, every sin and blasphemy will be forgiven men, but the blasphemy again the Spirit will not be forgiven men. vs 32 "any one who speaks a word against the Son of Man, it will be forgiven him, but whoever speaks against the Holy Spirit, it will not be forgiven him, either in this age or in the age to come. "
I've been doing more research about veniel and mortal sins -- they are RCC terms read about in the Catachism. That which the RCC calls them / what they are and how they are taken care of. Totally RCC. That which I shared in the above paragraph is what Scripture says. Soo - let's stay with Scripture.
