I grew up in the company of priests. My family had long ties to the parish and I had the freedom of visiting them whenever I wish. I spent many afternoons in the rectory eating snacks (they always had food!) while discussing theology. I was given a copy of the Good News Bible by our priest and would read it at night when I should be sleeping. My favorite books were Ecclesiastes, Sirach and The Wisdom of Solomon. I began praying for wisdom when I was ten.
Catholicism borrowed a great deal from Judaism. I'm not surprised that you're drawn to it. Most of our prayers are said in unison and there's a lot of standing and sitting. ;-)
I have never been to a Messianic synagogue. I attend a Reform one on occasion but feel most at home in Conservative settings. Shabbat service is four hours and is followed by challah and wine then kiddush lunch. The sense of community and belonging are what drew me near.
I don't believe I would have found my way back to God in a church. Religion and rhetoric might have driven me away. I wasn't won by dogma. The Holy Spirit was at the helm and that's the difference. My experiences have deeply impacted my witness and the way I share. I have infinite trust in His ability to woo His people because I've lived it firsthand.
But it's more than winning me back. Judaism is Home as well. That has never changed. I went to church, studied and served. But when I attended Rosh HaShanah services after a two-year absence I understood the ache I'd felt. And as we sang Avinu Malkeinu (listen to Streisand's version) I began to weep. I missed my people and longed to be with them once more.
I used to feel divided. My testimony is difficult for some because it wasn't a Christian that won me over. It doesn't fit the script that many have formed in their minds. Others read evangelism as its purpose without grasping I didn't receive the same.
As Frodo said,
"My dear Sam. You cannot always be torn in two. You have to be one and whole for many years. You have so much to enjoy and to be and to do. Your part in the story will go on."
And it has.
