Ecco,
If you are going to make accusations against the Church then why don't you go to it for a source relative to her teaching?
The Catholic Church in no official doctine teaches us to worship Mary. This is an anti-Catholic misrepresentation. The Church does teach Mary is an intercessor and we can pray (talk) to her in order to apeal to Christ (God). Even St. Paul exhorts us in scripture to intercede for one another through prayer and fasting.
Also the Church does not hold to Martin Luther's erronious teaching as do the separated denominations. Luther taught the Four Solas: sola fide, sola scriptura, sola spiritus and sola gratia. Of this list Catholic teaching agrees with only the latter "sola gratia" or salvation by grace alone. The Church teaches we must exercise faith (with love so it is not alone), accept scripture as part of divine relvelation (written and oral tradtion are the whole of revelation St. Paul refers too), and accept the third Person of the Blessed Trinity, the Holy Spirit, as necessary for our salvation.
No! We are saved by grace alone through faith in Jesus Christ, the Second Perons of the Blessed Trinity, and are endowed with the Holy Spirit who guides us in understanding both sacred scripture and oral tradition. This is official Catholic teaching and I must inform you that the Church was instituted by Christ when he set St. Peter as it's visible head to represent Christ (the Church's soul or invisible head) in his absence here on earth: "Thou art Peter and upon this rock I will build my church and the gates of hades will not prevail against it."
