Christ is Risen!
Water is not available they could pour as an "economia" but if the recepients were to survive they would have to be properly Baptised.
Ouch! Any priest doing a repeat of such baptism should be defrocked according to the sacred canons.
Many of the tens of thousands of Russians who have now emigrated to the West and come into the Russian Church Abroad have been baptized back in Russia by pouring. Your priest must have experience of this with new immigrants?
3 Immersions/Emmersions in the name of the Holy Trinity are not repeated.According to the sacred Canons a Man who has not been Baptized Canonically cannot become a cleric.In following the Lords command (Mt.28:19) we baptise in the name of the Father,Son,and of the Holy Spirit,3 times in succession.Our Lord and Saviour enunciated the 3 hypostases separately and distinctly.Canon L of the Holy Apostles and Canon VII of the second Ecumenical Council define triple immersion.
Best thing is ask Your ArchPastor what His thoughts are concerning what happened at St.Marks in Belgrade.Whats even a greater sin is that right behind St.Marks is the Holy Trinity Russian Church (where Saint John of Shanghai and SF was consecrated a Bishop,where the Kurst Root Icon dwelled)and where they Canonically Baptise both infants and Adults! The size of St Marks is 10-15 X the size of Holy Trinity.Many Serbs get Baptised there especially small children,since even them the official Serbian Church does not immerse.
I know for a fact that if Soviet/Russian immigrants ask and seek to be properly Baptized in ROCOR,especially if they are active and participate in the Church services our ArchPastors have given a Blessing for them to be Baptized Canonically.If the mystery Immersions/emmersions is omitted certainly quite a few prayers are also disregarded.Again,now, less and less Pastors and layfolk care to put themselves in front of the crowd heading towards modernism and don't want to (and can't handle) being blacklisted and following in the foot steps of Saintly Martyrs Nectarios,Nikolai,and John.The older Hierarchs of ROCOR would never allow their Priests to sprinkle or pour a candidate for Baptism,and if the Priest tried that shortcut He would be forced to properly Baptise the candidate,and would be suspended from serving the first time,and if He ever tried again to pour He would be defrocked!
