Bl. John Henry Newman, in writing to his old friend E.B. Pusey, wrote some very timely words of wisdom about the process of conversion one undergoes in becoming Catholic, particularly from an Anglican viewpoint. Here are some selections.
Of course, as you say, a convert comes to learn, and not to pick and choose. He comes in simplicity and confidence, and it does not occur to him to weigh and measure every proceeding, every practice which he meets with among those whom he has joined. He comes to Catholicism as to a living system, with a living teaching, and not to a mere collection of decrees and canons, which by themselves are of course but the framework, not the body and substance of the Church. And this is a truth which concerns, which binds, those also who never knew any other religion, not only the convert. By the Catholic system, I mean that rule of life, and those practices of devotion, for which we shall look in vain in the Creed of Pope Pius. The convert comes, not only to believe the Church, but also to trust and obey her priests, and to conform himself in charity to her people. It would never do for him to resolve that he never would say a Hail Mary, never avail himself of an indulgence, never kiss a crucifix, never accept the Lent dispensations, never mention a venial sin in confession. All this would not only be unreal, but would be dangerous, too, as arguing a wrong state of mind, which could not look to receive the divine blessing. Moreover, he comes to the ceremonial, and the moral theology, and the ecclesiastical regulations, which he finds on the spot where his lot is cast. And again, as regards matters of politics, of education, of general expedience, of taste, he does not criticize or controvert. And thus surrendering himself to the influences of his new religion, and not risking the loss of revealed truth altogether by attempting by a private rule to discriminate every moment its substance from its accidents, he is gradually so indoctrinated in Catholicism, as at length to have a right to speak as well as to hear. [...]
I prefer English habits of belief and devotion to foreign, from the same causes, and by the same right, which justifies foreigners in preferring their own. In following those of my people, I show less singularity, and create less disturbance than if I made a flourish with what is novel and exotic. And in this line of conduct I am but availing myself of the teaching which I fell in with on becoming a Catholic; and it is a pleasure to me to think that what I hold now, and would transmit after me if I could, is only what I received then. [...]
When I went to Rome, though it may seem strange to you to say it, even there I learned nothing inconsistent with this judgment. Local influences do not form the atmosphere of its institutions and colleges, which are Catholic in teaching as well as in name. I recollect one saying among others of my Confessor, a Jesuit Father, one of the holiest, most prudent men I ever knew. He said that we could not love the Blessed Virgin too much, if we loved our Lord a great deal more.
