No. Because no one can know real love outside of the Holy Spirit residing in them.
Considering someone can in fact know the unconditional Love of God, before they convert to a religion (think of how many examples there are of those who came to believe and converted in the NT), this poses a problem for what you are suggesting here. According to some people's theology, and I'll assume yours too, that you can't have the Holy Spirit in you until after you've been converted to the religion (something I do not believe). Than what are they responding to internally, if not that Love?
Scripture even says, "For it is by grace you have been saved, through faith—and this is not from yourselves, it is the gift of God". So inside of people who feel "called by God", there is that Spirit already in them in order for them to respond to it. They cannot be a
vacuum, and still respond. It's a case of "like recognizes like". How else is it that they can even respond to God, if it isn't God in them they are responding to? It says clearly, it "not from yourselves". It is therefore the Spirit of God, right?
And because love isn't the requirement for salvation... it's a fruit of salvation.
Wrong. It is the sole condition of salvation. But yes, it is also a fruit of it as well though. You doubt this? Let's ask Jesus.
"Teacher, which is the greatest commandment in the Law?”
Jesus replied: “‘Love the Lord your God with all your heart and with all your soul and with all your mind.’ This is the first and greatest commandment. And the second is like it: ‘Love your neighbor as yourself.’ All the Law and the Prophets hang on these two commandments.”
~Mt. 22:36-40
"Let no debt remain outstanding, except the continuing debt to love one another, for whoever loves others has fulfilled the law. The commandments, “You shall not commit adultery,” “You shall not murder,” “You shall not steal,” “You shall not covet,” and whatever other command there may be, are summed up in this one command: “Love your neighbor as yourself.” Love does no harm to a neighbor. Therefore love is the fulfillment of the law.
~Ro. 13:8-13
There are many others of course I can quote, but the point here is that in fact, if you do love as Jesus commanded, you are fulfilling the law of God. Are you saying that doesn't matter, you're still not saved, unless you swear fealty to certain religious doctrines? If so, then respond to this, "
For whoever does the will of my Father in heaven is my brother and sister and mother."
If you are fulfilling the law through Love, then you are doing the will of the Father, and Jesus calls you brother, and sister, and mother. And that would include anyone, anywhere, regardless of religious beliefs and doctrines and affiliations. "Love is the fulfillment of the law", teaches the scriptures.
The requirement is believe in Jesus, not some other god and definitely not in the self's ability to love.
No one is claiming the ego is the source of Love, with a capital L. God is the Source of that, and anyone can access that in themselves, if they open themselves to that. And that can happen for anyone, anywhere, regardless of their ideologies and beliefs.
But I ask you, what does "believe in Jesus" mean to you? Theological views? I've already shown that "believe" in scriptures is not primarily a mental thing. Yet that is what I seem to hear you suggesting, as you seem to ignore every point I've made showing it's not.
