I became a Christian in 2020 but I'm staying well away from Catholicism.

All you need to do to be a Christian is admit that Jesus Christ was the living God incarnated into human form. You must also admit that you are a sinner and confess your sins directly to Jesus and ask for his forgiveness because you want to be with Him in heaven in the afterlife.

You will become filled with the Holy Spirit and gain the armor of God as your protection from satans influence over you.
