I've gotten some questions about this recently, so I feel like I should articulate something that I maybe haven't done a great job of making clear: I decided to get baptized again out of obedience to the Word of God and as a public profession of my faith, NOT as a way to condemn or show preferential treatment to any particular denomination.
My decision to be baptized didn't have anything to do with denomination or a particular church. I think that all churches, regardless of denomination, have some variety of inherent flaws (they are, after all, composed of humans...). I believe God can (and does) use those flaws to teach us, to humble us, and to bring us closer to Him. I don't completely agree with Episcopal doctrine, nor do I completely agree with Baptist doctrine. I've discussed some of these (relatively minor) differences with my pastors, and we have agreed to respectfully disagree. They did make it clear that they value the fact that I am thinking critically for myself about the Scriptures, and not simply taking what they teach at face value without comparing it to God's Word. That, to me, spoke volumes about their character as teachers and pastors, and what they think is important in my relationship with the church and with God.
I chose the church I am currently attending based on the community that is growing there, and what I find spiritually nourishing - I have no particular issue with the Episcopal Church as a whole (or St. Timothy's in particular) that "drove me away" or caused me to leave - I simply find that a service constructed in a more ritualized, liturgical way is not as fulfilling or meaningful to me as a service with a little less structure and a little longer sermon. I don't think there's anything wrong with those types of services, and for some people (in particular, like my parents), they are wonderful. I just feel that at this point in my life, given who I am, it's simply not what I need. I believe that my church is very Biblical and Gospel-centered, and that the pastors and members are truly interested and invested in creating a community based in Christ. That is the most important thing to me.
Regarding baptism: my decision to be baptized is not my way of "officially switching denominations" or making any sort of declaration for the Baptist church or against the Episcopal church. It is not even really a part of me just becoming an official member of this particular church, but truly and fully becoming a part of His Church. Being baptized is something that God began to lay on my heart many years ago - before I fully rejected Him, even. I'm only choosing to be baptized with this new community because they truly have provided a communal home for me as my new life in DC grows, and as I grow in my walk with Christ.
I am not trying to undermine or downplay the importance of my parents and my upbringing in my spiritual walk. I simply acknowledge that at the age of 3 months old, I was not able to decide for myself to follow Christ wholeheartedly. I was never confirmed, nor did I ever take on the responsibility of that covenant with God for myself. My parents did in fact do their very best to raise me in a relationship with Christ. But I (and I alone) rejected that.
I believe that Jesus came to earth as fully man and fully God and replaced the old covenant with a new one of eternal grace and redemption, if we will only accept it. No matter how much my parents love me, or will me to the Gospel, or tried to raise me in a Christian life with a genuine relationship with God, they cannot make that decision for me. Because God, in his infinite love, gave us free will, I must own that decision for myself. And I have, finally. My baptism is not a condemnation of the Episcopal church, of the way my parents raised me, or a simple "re-acceptance" into the faith (we all experience ups and downs, even daily and hourly!). It is more than just a renewal of a covenant that I have already accepted - It is an acceptance of a covenant I have never taken part in until now. I did not decide to be baptized spontaneously or lightly; I have prayed through this decision and truly examined my heart in the matter.
Praise be to God for His infinite grace!
