To be sure, St Thomas also states that the intentional killing of the innocent or undue violence is a grave sin but violence in protection of ones self or another to the point of killing is does not prevent salvation.
I agree with St Thomas.
*** violence in protection of ones self or another to the point of killing is does not prevent salvation.***
Thinking through this...
I can think of no NT basis for the above statement. And though it does make sense from a certain perspective, we have comments like...
Matthew 5:39
But I say unto you, That ye resist not evil: but whosoever shall smite thee on thy right cheek, turn to him the other also.
Matthew 10:28
And fear not them which kill the body, but are not able to kill the soul: but rather fear him which is able to destroy both soul and body in hell.
Heb 12:3
Consider him who endured from sinners such hostility against himself, so that you may not grow weary or fainthearted.
Ultimately we shall be judged by the words of Christ - not Aquinas.
