Methinks the altars and temples of certain ones among these saints are not held to be idolatrous even though they are used for special sacrifices and prayers to their patrons.
Some, however, may perchance argue that churches are not built or altars dedicated to the Father because there is no feast which is solemnized especially for Him. But while this reasoning holds good as regards the Trinity itself, it does not apply in the case of the Holy Spirit. For this Spirit, from the day of Its advent, has had Its special feast of the Pentecost, even as the Son has had since His coming upon earth His feast of the Nativity. Even as the Son was sent into this world, so did the Holy Spirit descend upon the disciples, and thus does It claim Its special religious rites. Nay, it seems more fitting to dedicate a temple to It than to either of the other Persons of the Trinity, if we but carefully study the apostolic authority, and consider the workings of this Spirit Itself. To none of the three Persons did the apostle dedicate a special temple save to the Holy Spirit alone. He does not speak of a temple of the Father, or a temple of the Son, as he does of a temple of the Holy Spirit, writing thus in his first epistle to the Corinthians: "But he that is joined unto the Lord is one spirit." (I Cor. vi, 17). And again: "What? know ye not that your body is the temple of the Holy Spirit which is in you, which ye have of God, and ye are not your own?" (ib. 19).
Who is there who does not know that the sacraments of God's blessings pertaining to the Church are particularly ascribed to the operation of divine grace, by which is meant the Holy Spirit? Forsooth we are born again of water and of the Holy Spirit in baptism, and thus from the very beginning is the body made, as it were, a special temple of God. In the successive sacraments, moreover, the seven-fold grace of the Spirit is added, whereby this same temple of God is made beautiful and is consecrated. What wonder is it, then, if to that Person to Whom the apostle assigned a spiritual temple we should dedicate a material one? Or to what Person can a church be more rightly said to belong than to Him to Whom all the blessings which the church administers are particularly ascribed? It was not, however, with the thought of dedicating my oratory to one Person that I first called it the Paraclete, but for the reason I have already told, that in this spot I found consolation. 'None the less, even if I had done it for the reason attributed to me, the departure from the usual custom would have been in no way illogical.
