Within Christianity down through the centuries there has always been a strain of teaching which holds that salvation, so far as it may be known in this life, is experienced in two stages: first the event of becoming a Christian; then, as a later and distinct event, some special and distinctive operation or gift of the Holy Spirit. In the history of Christian thought this disjointedness was first clearly formulated in the Catholic sacraments of Baptism and Confirmation. According to A. J. Macdonald, the idea that Confirmation confers the gift of the Spirit was held without question until the time of Wyclif. And today in anglo-catholic tradition, although the episcopal laying on of hands is commonly thought of as bestowing a strengthening gift of the Spirit, some continue to speak as though the Spirit is first received at that time. Indeed, since the question was reopened by F. W. Puller in 1880, it has been regularly argued, often with great weight, though not infrequently with greater ingenuity, that far greater significance (in terms of the Spirit) should be attributed to Confirmation than to Baptism.
