Does “sacrament” have a meaning? According to many, a sacrament has “saving grace” connected. Their belief is clearly stated as follows.
“Holy Baptism and the Holy Eucharist are considered the two great Sacraments of the Gospel, as they are the two Sacraments instituted by the Lord himself unto salvation. Baptism and the Eucharist are the ordinary means by which God, through the Church, imparts His saving grace to the world”.
If this is the definition of Sacrament then it begs the question as to whether or not the researchers have ever carefully read the doctrinal statement of the Assemblies of God concerning the Baptism in the Holy Spirit and/or tongues as the initial physical evidence of have received said Baptism.
Simply put the Baptism in the Holy Spirit is an action wherein Jesus is the Baptizer. The Holy Spirit comes upon the recipient who now has an enduement of power for life and service.
Classical Pentecostals would generally reject the idea that the Baptism in the Holy Spirit and/or speaking in tongues have a saving grace connected. (Yes, there are a few exceptions)
The enduement of power enhances missional ability in many ways.
However, the argument that separates the groups may be like straining at a fly while swallowing a camel. Perhaps there is “some” saving grace in things like water baptism, covenant marriage, confirmation, Holy Communion, anointing the sick, reconciliation (confession), and or Holy Orders.
At least on this side of heaven those things, when done faithfully in a persons walk with Christ, being faithful in these things can an do “save” many from the destructions that sin brings upon mortal bodies and the homes that people live in.
In the words of Cyprian, bishop of Carthage, [Christians living in a world of sin] “We do not speak great things, but we live them”.
