Many consider that faith must be in the soul, but going to church isnt necessary. Is this so?
Those who say that faith must only be in the soul are making two substantial errors. First of all faith in the soul as a rule comes to an abstract and speculative recognition of Gods existence, out of which one almost cant make any real conclusions from in their life. Tying into that one can remember the words of Christ, that the devils also believe, and tremble (James 2:19). Such a person usually doesnt even tremble but lives as if there has never been a ransom sacrifice of Christ for each one of us. Second of all, this position can in no way be concluded from the Holy Scripture, nor from the Church tradition. Christ told us that He came to create on this earth a Church, not to create a mass union of God with individual people who are in no way tied to each other. He came to give the commandment of love not just to God, but to ones neighbor. Only this can bring about the completeness of man. A Christian commits acts of kindness not as some ancient hero and not as a model of communist/
