Update: ..pg 193 continues:
[If Christ is a fraud then the spectacle exhibited by the Church is a]...gigantic fraud. If not, however, then this spectacle is alas! only what was to be expected: it began before the first Easter, and it does not affect faith at all - except that we may and should be deeply grieved. But we should grieve on our Lord's behalf and for Him, associating with ourselves with the scandalizers not with the saints, not crying out that we cannot 'take' Judas Iscariot, or even the absurd and cowardly Simon Peter, or the silly women like James' mother, trying to push her sons.
It takes a fantastic will to unbelief to suppose that Jesus never really 'happened', and more to suppose that he did not say the things recorded of him - so incapable of being 'invented' by anyone in the world at that time: such as 'before Abraham came to be I am' (john viii). 'He that hath seen me hath seen the Father' (John ix); or the promulgation of the Blessed Sacrament in John v: 'He that eateth my flesh and drinketh my blood hath eternal life'. We must therefore either believe in Him and in what he said and take the consequences; or reject him and take the consequences. I find it for myself difficult to believe that anyone who has ever been to Communion, even once, with the right intention, can ever again reject Him without grave blame. (However, He alone knows each unique soul and its circumstances.)
The only cure for sagging or fainting faith is Communion. Though always Itself, perfect and complete and inviolate, the Blessed Sacrament does not operate completely and once for all in any of us. Like the act of Faith it must be continuous and grow by exercise. Frequency is of the highest effect. Seven times a week is more nourishing than seven times at intervals...
I myself am convinced of the Petrine claims, nor looking around the world does there seem much doubt which (if Christianity is true) is the True Church, the temple of the Spirit dying but living, corrupt but holy, self-reforming and rearising. But for me that Church of which the Pope is the acknowledged head on earth has a chief claim that it is the one that has (and still does) ever defended the Blessed Sacrament, and given it most honour, and put it (as Christ plainly intended) in the prime place. 'Feed my sheep' was His last charge to St. Peter; and since his words are always first to be understood literally, I suppose them to refer primarily to the Bread of Life. It was against this that the W. European revolt (or Reformation) was really launched - 'the blasphemous fable of the Mass' - and faith/works a mere red herring. I suppose the greatest reform of our time was that carried out by St. Pius X: surpassing anything, however needed, that the [Second Vatican] Council will achieve."
