Baptism cannot remit one sin because it is not a blood sacrifice.
Without the shedding of blood, there is NO remission of sins.
Scripture is very clear that what Jesus is doing in heaven RIGHT NOW, is sitting at the right hand of the Father, interceding for the saints. He is NOT being continually offered for sin for all eternity. The effectiveness in the sacrifice is due to the death of the sacrificed, not the act or process of being sacrificed.
If Jesus is still in the process of being sacrificed, the sacrifice is ineffective because death has not yet occurred. It’s not the dying that works, it’s the death, past tense.
Now you have me perplexed. I thought you said that you are a former Catholic and present yourself as an absolute expert on all things Catholic. That being the case, how could you be so terribly mistaken on the very core of the Catholic Liturgy, the Epiclesis, in which the one Sacrifice is made present during every Mass. Please do clear this up for me, I would hate that some might think less of your integrity over a simple misstatement.
Peace be with you.
