You should argue with Jesus about this.
Jesus taught that His disciples were to baptize others in the name of the Father, Son, and Holy Spirit (Matthew 28:19).
A person who is baptized in Jesus' name is someone who has believed in Jesus as Savior. This shortened version stated in Acts 2 and 4 did not negate what Jesus taught, but rather emphasized salvation exclusively in Jesus. The practice of the early church was to baptize in the name of the Father, Son, and Spirit as Jesus taught, emphasizing the Triune nature of God.
If that were actually true they would cease from praying to / talking to those that have died physically and have been separated from this world we are still living in.
Catholics are not Christians, they are not born again, and they are not going to Heaven.
That's because they follow man made catholic doctrine rather than what the Lord teaches in His Word.
You're not God, so you have zero contact with those separated from this world.
The sad thing is... you people reject Jesus as being the ONLY mediator between God and man... so you folks out calling on others when you should be praying directly to ther Father in Jesus Name as the Lord instructed His followers to do.
The catholics do not follow Jesus, instead they follow man made doctrine that is not of God.
Some object that the Catholic position on intercessory prayer is the same as necromancy, that is, calling upon the spirits of the dead to find out the future or obtain other information.
Necromancy is a grave sin that, far from fostering communion, shows a lack of faith and trust in God. Necromancy was punishable by death under the Mosaic law (Lev. 19:31, 20:6). Some of the early Israelites practiced necromancy, including Saul (1 Sam. 28:3, 8-14), and they were punished severely for doing so (1 Sam. 28:17-19). This practice offended God (2 Kings 21:6) and led to the destruction of Israel.
Catholics do not practice necromancy, which is explicitly forbidden by the Church (cf. Catechism, nos. 2115-17). Rather, they ask for the prayers of the saints to foster communion in the Family of God.
Seeking the intercession of the saints is not necromancy for two reasons:
First, necromancers are usually trying to receive information that they do not have, such as what will happen in the future. Asking the saints to pray for us, however, is not a form of divination or fortune telling.
Second, necromancers are also trying to bring back and control the souls of dead people. Catholics, on the contrary, believe that those who have died in God’s grace are not dead but truly alive, and are able to help us by their prayers. As Jesus says, “[Moses] calls the Lord the God of Abraham and the God of Isaac and the God of Jacob. Now he is not the God of the dead, but of the living; for all live to him” (Lk. 20:37-38).
According to Jesus, death cannot separate the faithful—such as Abraham, Isaac, and Jacob—from God. And, if they are alive to God, they must be alive to us through Him as members of His one body. Otherwise, contrary to what Saint Paul says, Christ’s victory over death was incomplete, and His body is not truly one (cf. Jn.17:21; 1 Cor. 12: 12,13; 15:14 et al).
