“When, therefore, I went into Boston and saw Bishop Fitzpatrick (who is now, I hope, in the kingdom of heaven), he had little to do with me in the way of instruction.  The Trinity and other fundamental doctrines I accepted readily on the authority of the Church.  He was very anxious to argue with me about socialistic theories, on account of my having been at Brook Farm and Fruitlands.  But I told him I had no such difficulties as he supposed; that I had only gone to these places in search of truth, not because I had formed any such theories as they generally held.  He then asked me whether I would not prefer to be received into the Church in New York, where my friends were.  I said I did not care; if he would give me a letter I would present it.  He gave me one to Bishop McCloskey, who was then coadjutor in this city.”

The reader may be interested in the terms in which the Catechism of the Council of Trent expresses the doctrine of the Communion of Saints.  So far as that doctrine concerns the spiritual side of man it is expounded in these words: 

“For the unity of the Spirit, by which the Church is governed, establishes among all her members a community of spiritual blessings, whereas the fruit of all the sacraments is common to all the faithful, and these sacraments, particularly baptism, the door, as it were, by which we are admitted into the Church, are so many connecting links which bind and unite them to Jesus Christ.”

That it extends to the mystical and miraculous gifts so dear to Father Hecker, was thus explained to him: 

“But the gifts which justify and endear us to God are not alone common:  ‘graces gratuitously granted,’ such as knowledge, prophecy, the gifts of tongues and of miracles, and others of the same sort, are common also, and are granted even to the wicked; not, however, for their own, but for the general good; for the building up of the Church of God.”

That the doctrine is the foundation of a real though not a legal community of material goods, was evident to our young social reformer from the following: 

“In fine, every true Christian possesses nothing which he should not consider common to all others with himself, and should therefore be prepared promptly to relieve an indigent fellow-creature; for he that is blessed with worldly goods, and sees his brother in want, and will not assist him, is at once convicted of not having the love of God within him.”

Besides giving him a letter to Bishop McCloskey, Bishop Fitzpatrick also furnished the young catechumen with one to the president of Holy Cross College, an institution which had been established at Worcester, Mass., in 1843 by Bishop Fenwick, and presented by him to the Society of Jesus, of which he had been a member.  The following letter was written by Isaac to his family after he had arrived there; his stay was not long:
