Broad and complete you say? Wow, that's quite the statement. Is that complete in the sense that an angel has full and complete knowledge? I don't know a Catholic who would ever boast of 'knowing it all.' Once again the gnosis of Protestantism peeks its head up. .
But lets run with that for a moment. If the protestant apologist has complete knowledge of everything that it is to be a Christian then how can they possibly offend God with sin if their knowledge is so complete? Unless an act of transcendence has occurred. Their humanity has been left behind for some other order of existence.
P.S.: Catholic theology is Christian. Another artificial bifurcation from team Luther/Zwingli/Calvin.
“....Catholic theology is Christian....”
No it is not...but catholics do think/believe it is, sadly to their own hurt.
..... Which is why believers who practice true Christianity cannot agree with catholic practices and traditions, which Jesus clearly taught not to do or be.
I’ll repeat...(since you misquoted my words).....Christians posting do have a broad and complete understanding of Christian Theology......and just so you understand....all of that rests firmly ‘on the person of Jesus Christ’, who says we are “complete” in Him....Further, He gave us His word...and in case you need to be refreshed....The “Word of Christ” IS the Christian doctrine.
As is written....Let ‘the word of Christ’ dwell in you richly in all wisdom....For the LORD gives wisdom, from His mouth come knowledge and understanding....Col.3 /Prov. 2
and further as is written.....“As you therefore have received Christ Jesus the Lord, so walk ‘in Him’,..... rooted and built up ‘in Him’..... and established in the faith, as you have been taught, abounding in it with thanksgiving..... Beware lest anyone cheat (“plunder you or take you captive”) you through ‘philosophy’’’ and ‘empty deceit’,’’’ according’ to the tradition of men’, ‘’’according to the basic principles of the world, and not according to Christ.’’’’’ For in Him dwells all the fullness of the Godhead bodily; and you are complete in Him, which is the head of all principality and power...Col.2
