We are Saved by Grace,

We are Saved by Grace,
and Kept by Works.
Salvation history doesn't lend itself to slogans very well. The Church takes much greater pains to explain deep theology in such bodies of work as the Summa Theologica, Papal Encyclicals, the homilies and writings of the Doctors of the Church, et al, than can adequately be explained through trite jargon. When you try, you set up straw men arguments that are nothing but nonsense... they make you feel superior to your target but truly say nothing about the subject.
If you want to attack Church theology, I recommend you read an actual body of work rather than tracts about bodies of work you've never read.
