What is the Roman Catholic method of salvation? Evangelicals believe that salvation is by grace alone through faith, that Christ's death and resurrection alone is the basis of their Salvation.  Is this comparable to the Roman Catholic concept of salvation?
The Catechism is quite clear. Faith is absolutely necessary.


  161 Believing in Jesus Christ and in the One who sent him for our salvation is necessary for obtaining that salvation.42 'Since "without faith it is impossible to please (God)" and to attain to the fellowship of his sons, therefore without faith no one has ever attained justification, nor will anyone obtain eternal life "But he who endures to the end".'43


The Catholic Church subscribes to the historic creeds, including the Athanasian Creed (see CCC192)

42 Cf. Mk 16:16; Jn 3:36, 6:40 et al.
43 Dei Filius 3; cf Mt 10:22, 24:13; Heb 11:6; Council of Trent
