Believe, yes...which is the basis of faith. But neither are actions or works, they are what is in the heart. The scriptures (James) then say that having belief and faith (inwardly) in our hearts, if given the opportunity, it will indeed result in good works. This is confirmed of salvation, by Jesus saying, "the kingdom of God is within you." But that does not speak of when or how we are saved, nor is it required, but it speaks rather of the result of salvation for "those who are alive and remain" in the world.
covenants require an outward sign and not faith alone
1 cor 3:2 “all faith” without charity avails nothing
Phil 1:29 not called to faith alone
Faith alone apart from the sacraments
