Shalom,
Alrighty then... who wants to talk to a Catholic? I'm here! I was born and raised in a Catholic home and went through all the sacraments... except for the last one of course. ;-)
How did I get to here and leave everything Catholic behind? Well, I read and listened. First it was the books and magazines from the Worldwide Church of God, then it was the YY site. Could anyone else do it? Of course! If they were drawn by Yahweh and were truly seeking Him! Otherwise, it's just a lot of empty words.
Those who are drawn cannot claim anything themselves for they were not the ones to initiate the relationship. Then, they have to want to be involved in having a relationship with the Creator. They show this through their actions: seeking Him. If they are insincere in wanting to get to know Him after being called, little will move them. So their desire is important, but it is important for them to show it because only then will Yahweh share His Set-Apart Spirit with them! Without the Ruach haQodesh, we would not be able to learn the things of Yahweh!
This is why when people are not truly sincere in their search, they tend to land up in a church. But sometimes, their sincerity is bound up by the teachings of the clergy. And not knowing any better, they are left outside of a deeper relationship with Yahweh. Instead, they fall prey to religious guile and force. Would Yahweh abandon them at the GWT judgement? His mercy knows no bounds so I will not say that they are unsaved. But those who know they are wrong but continue to live a lie and promote lies leading others away from Yahweh, Scripture says that their fate is worse than death.
What I will focus on is how to share the Truth about Yahweh with those who are truly seeking Him. I am still quite wary of how Truth will affect familiar relationships, but I am now less inhibited than before. The first thing is to be committed and unafraid. Then only can you share the Good News of The Word without reserve.
I have spoken to friends who are Catholics and non-Catholics, and the response is the same. So it does not matter. Debunking Catholicism to Catholics is not a great strategy. A better one is to share Truth first. Show the Word and tell them what it really means. Show them why Yahweh's name, Annointed One and timeline matters, and how to understand Scripture better. Just telling them that the pope is misguided and that they got things wrong with Easter and Christmas and Sunday won't cut it. They have to know the name of the Father they pray to! They have to know what His name means to those He has called! They have to understand that there is only one continuing covenant, and not separate ones for Jews and Christians.
Start small with tracts that explain these things. Some of the pamphlets on
www.eliyah.com may work for you in your outreach. Check it out to see if it stands with (y)our beliefs before you give it out. Otherwise, just choose your favourite Scripture verses and print those out and put it everywhere so that it initiates conversation. If they are really interested, give them the link to YY. If they do not have Net access, print out some chapters for them. That's what it's about. Be a light. Notice how light is not forceful but powerful in illuminating the dark? Like salt we are scattered around the world. We are called to be Yahweh's flavoring upon this world, wherever we are. We do what we can because we truly believe in His Kingdom, His Family, not because we want to rack up membership numbers. Don't be a battering ram. Ain't gonna work well. You fight against the powers and principalities of the world.
Well, that's my two cents about approaching Catholics. Approach them like you would any other -- honestly, openly and faithful to Yahweh.
