Your stated “fact” of Patriarchal and Matriarchal Christianity is all new to me (and I too am Catholic). No doubt you have heard of Purgatory? That is where the Church says, yes, you may be saved in those last 10 seconds but there is still some perfecting to be done before sharing God’s eternal glory. There are references to this process in the Bible. And, “If he is a God of love, then He is incapable of any other emotion” . Are you sure you want to place such a limitation on GOD? We are currently living in a period of Divine Mercy while He is calling us back to
Himself, to be followed by His Divine Justice. This is how He described it to Saint Faustina in the 1930s.(see her diary of Jesus’ revelations to her about Divine Mercy. (She was canonized by John Paul II just before he died).
One result is that we now have the feast of Divine Mercy on the 1st Sunday after Easter. It is a great gift, check it out.
