In the Catholic definition, faith is an intellectual assent to a loving God and his revelation to us. Faith is a grace as it is undeserved help. Faith requires a free human response as we must listen and respond to god's call. Faith is a risk. Faith is reasonable as we do not blindly trust in it. Faith is certain as we know we believe and stick to our opinion. Faith seeks understanding. Faith is also a virtue which is goodness or right action and thinking.

Do I sometimes have blind faith? I do cause sometimes I can not stand for these beliefs not to be true as said in Second Hand Lions "You believe in them because they are worth believing in, doesn't matter wheter they are true or not." Therefore I believe in some things despite lack of evidence to back me up because my mind needs it to be true.
