I am seriously asking where is the ‘communion of saints’ taught ?? When I was a child it was taught simply as a fact with no explanation of the source..
I had accepted it as a fact, now wondering its source ..no trick my friend
The communion of saints is the Church. The term "communion of saints" therefore has two closely linked meanings: communion in holy things (sancta)" and "among holy persons (sancti)."
Sancta sancti's! ("God's holy gifts for God's holy people") is proclaimed by the celebrant in most Eastern liturgies during the elevation of the holy Gifts before the distribution of communion. The faithful (sancti) are fed by Christ's holy body and blood (sancta) to grow in the communion of the Holy Spirit (koinonia) and to communicate it to the world.
Since Abraham, intercession - asking on behalf of another has been characteristic of a heart attuned to God's mercy. In the age of the Church, Christian intercession participates in Christ's, as an expression of the communion of saints. In intercession, he who prays looks "not only to his own interests, but also to the interests of others," even to the point of praying for those who do him harm. Phil 2:4; cf. Acts 7:60; Lk 23:28, 34.
