"Conversely, my Catholic Mom definitely has a fully biblical worldview."
No offense taken. Of course exactly what it means to have "a fully Biblical worldview" is not at all agreed upon between Catholics and non-Catholics. Non-Catholics and Catholics would dispute exactly what this means, with both claiming the others' views are not exactly "fully Biblical," so I think this article, as it is posited, is not very useful.
Every baptized Christian (which is what makes one a Christian) has a different understanding of what "fully Biblical" means and has a greater or lesser understanding of the practice of the fullness of the Faith that Christ left the Apostles and His Church.
You just HAD to start it; didn't you!
Bling, bling, bling. Wrong statement!
Was the thief on the cross baptized? If so, when?
"Every baptized Christian (which is what makes one a Christian)"
Pardon me, but baptism doesn't make one a Christian any more than attending a particular church does.
A "Christian" is a person that has realized(by the intervention of the Holy Spirit) they are a helpless sinner that cannot save themselves from that sin. They recognize their sin separates them from God and they are fit only for hell. In Jesus Christ they perceive the only hope they have of pardon. So, by faith(also a gift from God) they put their whole trust in Christ (God the Son) and Him alone as the means to be saved from both the penalty and power of sin over them. As the old hymnn goes, "nothing in my had I bring, simply to thy cross I cling."
No ritual, like Baptism, makes one a Christian. However, once one has placed their trust in Christ alone, they will submit to Baptism because Jesus commanded it. A Christian will be obediant to their master (Jesus Christ). They will not be sinless, but they will strive to be so (repentance).
I guess this is WHY Jesus (of Nazareth) became the Messiah, becuase HE was BAPTIZED.
